Stainless Steel Thin Head Open-End Plain Body Blind Rivet Nuts

Technical Specifications — Stainless Steel Thin Head Open-End Plain Body Blind Rivet Nuts

Low-Profile Threaded Insert Design for Sheet Metal Assemblies

JUXIN FASTENERS stainless steel thin head open-end plain body blind rivet nuts are designed to create mechanically retained female threads in thin sheet metal,

 hollow sections and fabricated equipment housings.

The product combines a low-profile flange, a smooth cylindrical body and an open-ended internal thread.

Its primary engineering advantage is the ability to provide a threaded fastening point while minimizing flange projection above the mounting surface.

This configuration can be useful where equipment covers, mounting brackets and adjacent components must fit closely against the parent material.

Unlike knurled or hexagonal rivet nuts, the plain round-body design does not rely on external ribs or noncircular geometry for additional rotational engagement.

Selection must therefore consider mounting-hole accuracy, parent-material strength, installation quality and expected tightening torque.

Product Technical Data

The stated grip range is a product-family reference. Individual thread sizes and body lengths must be selected according to the applicable dimensional drawing.

The exact flange thickness, body diameter, overall length, installation-hole diameter and usable thread dimensions should be confirmed before engineering approval.

Thin Head Geometry and Installed Surface Clearance

The low-profile flange is the defining characteristic of this product.

Compared with a conventional flat-head rivet nut having a thicker flange, a thin-head design reduces the height of the fastening point above the parent surface.

This can be valuable when the assembled components must sit close together or when limited clearance is available beneath a cover or bracket.

However, low-profile does not necessarily mean completely flush.

The final installed projection depends on flange thickness, panel flatness, installation-hole condition and flange seating.

For applications requiring a precise surface height, engineers should specify the maximum permitted head projection in the product drawing.

Where the assembly requires a truly flush surface, a suitable countersunk insert may be more appropriate.

Thin Head Versus Standard Flat Head Rivet Nuts

A standard flat-head rivet nut generally provides a more substantial flange-bearing surface.

A thin-head rivet nut prioritizes reduced surface projection.

This creates an engineering trade-off between head clearance and flange-bearing geometry.

For thin or relatively soft panels, the flange and surrounding material must be capable of supporting the intended loading.

A reduced flange profile should not automatically be assumed to provide the same axial retention or pull-through performance as a larger flange design.

The appropriate configuration depends on panel strength, mounting-hole dimensions, service loading and installation conditions.

Where axial loading is demanding, representative pull-out and pull-through testing may be necessary.

Plain Round Body and Anti-Rotation Considerations

The smooth cylindrical body is designed for installation in an appropriately dimensioned round hole.

During setting, the deformable section of the rivet nut compresses behind the panel and forms a retaining bulge.

The installed fastener is mechanically retained between the flange and the blind-side deformation.

Because the body is smooth, its resistance to rotation depends on the interaction between the installed rivet nut and the parent material.

An oversized mounting hole may reduce rotational resistance.

An incorrectly set rivet nut may rotate during mating bolt installation or removal.

For applications involving higher tightening torque or repeated servicing, engineers should evaluate whether a knurled round-body or full-hex rivet nut is more suitable.

The correct choice should be based on the required installed performance rather than nominal thread size alone.

Open-End Configuration and Bolt Engagement

The open-end construction allows a mating bolt to pass through the threaded insert.

This provides flexibility when the required bolt engagement or component stack thickness varies.

It also means that the bolt may protrude beyond the rivet nut into the space behind the panel.

For hollow structures, equipment housings and compact assemblies, this protrusion must be checked against nearby components.

The designer should verify mating bolt length, required thread engagement, blind-side clearance and the final installed geometry.

Unlike a closed-end rivet nut, an open-end insert does not provide an enclosed threaded cavity.

Where a direct passage through the fastening point is unacceptable, a closed-end alternative should be considered.

Grip Range and Thin-Sheet Installation

The stated product-family grip range is 0.5–3.5 mm.

Grip range refers to the parent-material thickness or captured material stack thickness that a particular rivet nut configuration is intended to retain.

Correct grip selection is essential because the body must deform in the intended region behind the panel.

If the workpiece is too thin or too thick for the selected variant, the retaining bulge may form incorrectly.

This can affect axial retention, rotational resistance and flange seating.

For assemblies involving multiple layers of sheet metal, the actual captured stack thickness should be established before selecting the rivet nut.

The complete family grip range should not be interpreted as the permitted range for every individual size.

Mounting-Hole Dimensions and Hole Preparation

Mounting-hole geometry is critical to the performance of plain-body rivet nuts.

The hole diameter must permit insertion while supporting the required installed retention.

An oversized hole may allow unwanted movement or reduce resistance to rotation.

An undersized hole may prevent correct seating or damage the fastener and surrounding panel.

Hole roundness, burr condition, panel flatness and surface coating thickness can also influence the installation result.

For punched holes, engineers should consider edge quality and burr direction.

For drilled holes, dimensional accuracy and appropriate deburring are important.

The actual hole diameter and tolerance must be obtained from the approved product drawing.

Installation in Pre-Coated and Painted Panels

Low-profile rivet nuts may be used in selected pre-coated or painted sheet-metal assemblies, provided the installation process is compatible with the coating system.

However, installation can create local contact pressure and deformation around the mounting hole.

The process should not be assumed to leave every coating undamaged.

For coated panels, engineers should evaluate flange seating, coating thickness, possible cracking or abrasion and the effect of installation on corrosion protection.

Where coating integrity is critical, representative installation trials should be performed.

The installation sequence should be selected according to the customer's finishing and assembly requirements.

One-Sided Installation and Setting Equipment

Stainless steel thin-head rivet nuts can be installed using compatible manual, pneumatic, hydro-pneumatic or automated setting equipment, 

depending on the selected product and production requirements.

The installation tool engages the internal thread and applies axial force to deform the body behind the panel.

The resulting retaining bulge secures the rivet nut without requiring access to the rear side.

The setting mandrel must match the internal thread, and the nosepiece must support the low-profile flange correctly.

Stainless steel inserts may require different setting parameters from comparable aluminum or carbon steel variants.

Insufficient setting can produce inadequate retention.

Excessive setting can damage the internal thread, distort the flange or deform the parent material.

For OEM production, the setting process should be established and validated using representative workpieces and actual installation equipment.

Blind-Side Clearance and Installed Geometry

Although installation is performed from one side, sufficient space is required behind the panel.

The uninstalled rivet nut body must fit within the available cavity.

During installation, the deformable section forms a retaining bulge behind the workpiece.

After installation, the mating bolt may also extend through the open end.

These dimensions must be evaluated together.

For compact equipment, the limiting factor may be the installed body length or bolt protrusion rather than the low-profile head.

Engineers should therefore review both accessible-side and blind-side clearances during product selection.

Torque-to-Turn Resistance and Joint Reliability

Torque-to-turn resistance describes the ability of the installed rivet nut to resist rotation within the parent material.

This is different from the strength of the internal thread or the tightening torque applied to the mating bolt.

Plain-body rivet nuts may provide suitable rotational retention in correctly designed and installed assemblies.

However, they should not automatically be selected for demanding anti-rotation requirements without validation.

The installed performance depends on panel material, hole dimensions, grip thickness and setting parameters.

Where the connection is repeatedly assembled or serviced, rotational retention should be assessed under representative conditions.

If the insert rotates during bolt removal, maintenance may become difficult and the surrounding panel may be damaged.

Pull-Out, Pull-Through and Thread Integrity

The axial retention of a blind rivet nut depends on the interaction between its flange, retaining bulge and parent material.

Under excessive axial loading, the insert may pull out of the mounting hole or the surrounding panel may deform.

The flange-bearing region may also become a limiting factor.

For thin-head configurations, the relationship between flange dimensions and panel strength deserves particular attention.

Thread stripping is a separate failure mechanism involving the internal thread, mating bolt and engagement conditions.

Engineering acceptance criteria should distinguish rotational retention, axial retention and thread strength.

The appropriate test requirements depend on the actual application and loading conditions.

Stainless Steel Grade and Corrosion Selection

The supplied product information identifies stainless steel but does not establish one specific grade for every variant.

A2 stainless steel is commonly associated with 304-type austenitic stainless steel.

A4 stainless steel is commonly associated with 316-type compositions and may be evaluated for certain more demanding corrosion environments.

The actual grade and availability must be confirmed through the approved material specification.

Corrosion performance depends on environmental exposure, surface condition, temperature, moisture and contact with dissimilar metals.

Where stainless steel rivet nuts are installed in aluminum or coated carbon steel, galvanic corrosion should be considered if an electrolyte is present.

Material selection should reflect the complete joint rather than the rivet nut alone.

International Engineering References

Metric thread designations may be established using ISO 261, with applicable thread tolerances specified under ISO 965.

Where Unified inch-thread configurations are requested, ASME B1.1 may provide a relevant engineering reference.

The standard product information supplied for this page identifies metric M3–M10 sizes. UNC and UNF thread availability should not be assumed without separate confirmation.

Relevant ASTM or EN material specifications may be selected according to the actual stainless steel grade and customer requirements.

These standards provide engineering references but do not independently establish certification or compliance for a specific product.

Application Engineering for Electrical Enclosures

Electrical cabinets, control panels and fabricated equipment housings may require retained internal threads in thin sheet-metal walls.

Low-profile rivet nuts can reduce head projection where covers or mounting brackets require limited surface clearance.

The open-end configuration must be considered when the equipment contains components close to the blind side.

Where environmental sealing is required, a different fastening configuration or additional sealing arrangement may be necessary.

Application Engineering for Electronics and Instrumentation

Compact electronics and instrumentation housings may benefit from a reduced flange profile.

The design can be useful where a conventional flat-head rivet nut would interfere with adjacent components.

Engineers should verify the installed head height, usable thread engagement, bolt protrusion and available internal clearance.

Application Engineering for Automotive and Transportation Equipment

Automotive brackets, service panels and fabricated equipment housings may require one-sided threaded connections.

Thin-head rivet nuts can be evaluated where low surface projection and assembly access are important.

For vibration-sensitive applications, engineers should assess tightening torque, rotational retention, panel strength and joint preload.

Safety-critical applications require project-specific validation.

Application Engineering for Industrial Machinery

Machinery covers, guards and removable equipment panels may require permanent female threads in thin metal structures.

Low-profile rivet nuts can be useful where a thicker flange would interfere with a cover or mounting component.

For assemblies requiring repeated bolt removal, rotational retention should be evaluated against the expected maintenance conditions.

Application Engineering for HVAC and Appliance Manufacturing

HVAC equipment, ventilation housings and domestic appliance assemblies often incorporate thin sheet-metal components.

Low-profile rivet nuts can provide retained threads where one-sided access is required and surface clearance is limited.

The correct product should be selected according to panel thickness, installation-hole geometry, corrosion exposure and mechanical requirements.

Quality Inspection and Production Approval

For OEM production, inspection requirements should reflect the intended application and approved product specification.

Relevant dimensional characteristics may include thread size, flange thickness, flange diameter, body diameter, overall length and installation-hole compatibility.

Installed-joint evaluation may include flange seating, retaining bulge formation, thread integrity, rotational retention and axial retention where required.

For coated panels, the effect of installation on the surrounding surface may also need to be evaluated.

The inspection plan should distinguish product dimensional conformity from installed-joint mechanical performance.

Technical RFQ and Procurement Requirements

For an accurate quotation, please provide the required thread size, stainless steel grade, parent-material thickness, mounting-hole dimensions and product drawing.

For thin-head applications, the maximum permitted flange projection is particularly important.

For open-end applications, the mating bolt length and available blind-side clearance should also be identified.

Where mechanical performance is critical, the required torque-to-turn, pull-out or other acceptance criteria should be specified.

Estimated annual demand, order quantity, sample requirements, inspection expectations and packaging instructions will support the technical and commercial review.

Why Engineers Choose Thin Head Rivet Nuts

In many fabricated assemblies, the available space above the mounting surface is limited.

A conventional flanged rivet nut may create unwanted interference beneath a close-fitting bracket, cover or adjacent component.

A thin-head rivet nut reduces this projection while retaining the ability to create a mechanically secured internal thread.

This can simplify assembly design where a low-profile fastening point is needed without machining a full countersink.

However, a thin head is not automatically flush with the panel surface. The final projection depends on the actual flange thickness, seating condition and panel geometry.

Where a fully flush surface is required, the engineer should evaluate the actual installed dimensions and consider a countersunk configuration if appropriate.

Open-End Design for Flexible Bolt Engagement

The open-end configuration permits the mating bolt to extend through the threaded insert.

This can provide greater flexibility in bolt engagement than a closed-end rivet nut with a finite internal cavity.

It may be useful where different attached component thicknesses or bolt lengths are involved, provided sufficient space is available behind the panel.

The designer must still verify thread engagement, bolt protrusion and interference with internal components.

Because the threaded bore is open, the fastener does not create a sealed barrier through the mounting point.

For applications requiring environmental sealing, a closed-end or dedicated sealed rivet nut should be evaluated.

Plain Round Body for Round-Hole Installation

The smooth cylindrical body is intended for installation in a round mounting hole of the specified diameter.

During installation, the deformable portion of the rivet nut body collapses behind the panel to form a retaining bulge.

The flange and retaining bulge mechanically secure the insert to the workpiece.

Unlike knurled or hexagonal body designs, a plain round body does not introduce external ribs or a matching noncircular geometry for additional rotational engagement.

Its resistance to rotation therefore depends heavily on the installed deformation, contact conditions, mounting-hole dimensions and parent-material properties.

Where high tightening torque or repeated servicing creates demanding rotational loads, engineers should assess whether a knurled or full-hex alternative would provide a more suitable solution.

Stainless Steel Construction

Stainless steel is commonly selected for industrial fasteners where corrosion resistance, durability and material compatibility are important.

For low-profile rivet nuts used in equipment housings, electrical assemblies and fabricated components, stainless steel may provide advantages over unprotected carbon steel in suitable environments.

The exact material grade must be confirmed according to the approved specification.

A2 stainless steel is commonly associated with 304-type austenitic stainless steel, while A4 stainless steel is commonly associated with 316-type compositions.

These are material-selection references rather than confirmed grade options for every product variant.

For outdoor or chloride-containing environments, the material selection should consider the actual exposure conditions and compatibility with the surrounding panel.

One-Sided Installation in Thin and Hollow Materials

Blind rivet nuts create mechanically retained internal threads without requiring access to the rear side of the workpiece.

A compatible installation tool engages the internal thread and applies an axial setting action.

The deformable body section compresses behind the panel, creating a retaining bulge that secures the insert.

This method can be useful for fabricated cabinets, tubular sections, sheet-metal housings and hollow profiles.

The product-family grip range of 0.5–3.5 mm supports selection for suitable thin-material applications, but the correct grip range must be verified for each size and body length.

Installation quality depends on the mounting-hole dimensions, parent-material properties, tool compatibility and setting parameters.

Engineering Applications

Electrical Enclosures and Control Cabinets

Low-profile rivet nuts can be considered for mounting brackets, removable panels and internal equipment supports where head projection must be minimized.

The open-end design provides flexibility for bolt engagement, while the stainless steel construction may be suitable for selected industrial environments.

Electronics and Instrumentation

Compact equipment housings often have limited space between adjacent components.

Thin-head threaded inserts may reduce interference at the mounting surface and support serviceable screw connections.

Engineers should review flange projection, internal bolt protrusion and blind-side clearance.

Automotive and Transportation Equipment

Automotive brackets, interior equipment housings, service panels and fabricated structures may require threaded fastening points in thin sheet metal.

Low-profile rivet nuts can be evaluated where assembly clearance and one-sided access are important.

For vibration-sensitive applications, rotational retention and joint preload should be validated.

Industrial Machinery and Equipment Panels

Machinery guards, equipment covers and removable panels often require permanent female threads that remain attached to the workpiece.

Thin-head open-end rivet nuts can provide a practical fastening option where a conventional flange would interfere with nearby components.

HVAC and Climate-Control Equipment

Ventilation housings, sheet-metal covers and equipment brackets may benefit from one-sided installation and a reduced flange profile.

The engineer should consider material thickness, corrosion exposure and the required fastening performance.

Domestic Appliances and Consumer Equipment

Selected appliance housings and sheet-metal assemblies may require low-profile threaded fastening points for brackets, covers and serviceable components.

The suitability of the rivet nut depends on the surrounding material, installation geometry and expected loading.

General Sheet Metal Fabrication

Thin-head plain-body rivet nuts can be used in appropriate fabricated metal components where round-hole installation and limited head projection are desired.

They may provide an alternative to loose nuts or directly tapped thin sheet material when a retained internal thread is required.
