Flat Head Open end Round Body Plain Blind Rivet Nuts

Technical Specifications — Brass Blind Rivet Nuts

Product Specifications

Metric Thread Reference

The following pitches correspond to standard ISO metric coarse threads. The actual thread specification must be verified against the product drawing.

Thread designation and tolerances should be defined using applicable ISO metric thread specifications, including ISO 261, ISO 724, and ISO 965 where relevant.

These standards describe thread requirements; they do not establish the dimensions or performance of the complete blind rivet nut.

Engineering Selection and Installation Guide

1. Brass Material Selection

Brass offers electrical conductivity, formability, and corrosion behavior that differ from carbon steel and stainless steel.

Material selection should account for the specific brass alloy, service environment, mechanical loading, and mating materials.

For drawing-based OEM orders, the brass grade and material condition should be established using an agreed specification. 

ASTM or EN material specifications may be referenced where applicable to the selected alloy and product form.

Brass components should not be assumed suitable for high-load structural connections without appropriate mechanical verification.

2. Mounting Hole and Panel Compatibility

The smooth round body is intended for installation in a correctly dimensioned mounting hole.

Engineers should verify:

• Mounting hole diameter and tolerance

• Panel thickness and material

• Hole edge condition and burr removal

• Flange contact surface

• Minimum edge distance

• Clearance behind the panel

An oversized mounting hole may reduce resistance to rotation. Incorrect hole preparation or panel deformation can also affect installation quality.

3. Grip Range Selection

The published grip range of 0.5–6.0 mm represents the available product series, not a guaranteed range for every thread size.

The selected part must match the actual panel thickness and the individual product drawing.

For soft panels, coated sheets, or assemblies with variable thickness, sample installation testing is recommended.

4. Brass Deformation During Installation

Blind rivet nuts are installed by applying axial force through a compatible setting tool, causing the designated body section to deform behind the mounting panel.

Because brass deformation behavior depends on alloy composition, material condition, and part geometry, installation parameters should be established for the specific component.

Excessive setting force or stroke can damage the internal thread, distort the flange, or compromise the installed joint.

Insufficient setting may result in poor retention.

5. Spin-Out and Pull-Out Resistance

Two important installation performance characteristics are:

Spin-out resistance: The ability of the installed rivet nut to resist rotation when tightening or loosening a mating screw.

Pull-out resistance: The ability of the installed rivet nut to resist axial extraction from the mounting panel.

Both depend on rivet nut geometry, brass material properties, panel material, mounting hole dimensions, and installation conditions.

A smooth round-body rivet nut should not be assumed to provide the same anti-rotation performance as a knurled-body or hex-body insert.

For repeated maintenance or higher tightening torque, evaluate an alternative body configuration if necessary.

6. Electrical Conductivity and Grounding

Brass is electrically conductive, making it a potential material option for selected electrical and electronic equipment assemblies.

However, electrical continuity through an installed rivet nut depends on surface condition, contact pressure, coatings, oxidation, and the complete joint design.

A brass rivet nut must not be treated as an approved grounding or protective bonding connection without application-specific validation.

7. Corrosion and Galvanic Compatibility

Natural brass can be suitable for certain indoor and mildly corrosive environments, depending on the alloy and exposure conditions.

When brass contacts aluminum, steel, or other dissimilar metals in the presence of moisture, galvanic corrosion risk should be evaluated.

Brass alloys may also be susceptible to environmental degradation, including stress corrosion cracking under certain conditions.

For marine, outdoor, chemical, or high-humidity applications, confirm the actual environmental requirements before material approval.

8. Open-End Configuration and Screw Length

The open-end design allows the mating screw to extend beyond the threaded insert when sufficient clearance is available.

Engineers should confirm:

• Mating screw thread compatibility

• Available thread engagement

• Screw length

• Backside clearance

• Potential interference with nearby components

Open-end brass rivet nuts do not provide an inherently sealed connection.

9. Installation Validation

For OEM production approval, evaluate representative samples for:

• Correct mounting hole fit

• Proper backside deformation

• Flange seating

• Thread integrity

• Spin-out resistance

• Pull-out resistance

• Repeated screw assembly where applicable

• Corrosion and electrical performance where required

Typical Industrial Applications

Brass blind rivet nuts may be selected for electrical equipment housings, electronic instrument enclosures, control panels, lighting assemblies, decorative metal components, equipment cabinets, and light-duty fabricated structures.

Their electrical conductivity and non-ferrous composition may be relevant to certain equipment designs, but electrical continuity, grounding performance, and corrosion compatibility must be validated at the assembly level.

Engineering Selection

Brass is generally softer than many commonly used steel fastener materials. Engineers should therefore evaluate installation deformation, thread strength, spin-out resistance, and pull-out performance rather than substituting brass directly for an existing steel rivet nut.The smooth round body also requires careful mounting hole control, particularly where repeated screw tightening may apply rotational loads.
