Low-Profile Closed-End Full-Hex Blind Rivet Nut

Technical Specifications – Thin Head Closed-End Full Hex Steel Rivet Nuts

Standard Product Specifications

The grip range shown represents the overall product family. Each individual configuration must be selected according to its approved drawing and installation requirements.

Metric Thread Specifications

These pitches are standard ISO metric coarse-thread references. Exact internal thread requirements should be verified against the applicable product drawing.

Full Hexagonal Body Design

The full hexagonal body provides mechanical engagement with a matching hexagonal hole.

This geometry helps resist insert rotation during screw tightening and removal.

The performance depends on the following factors:

• Hexagonal hole across-flats dimension

• Hole tolerance and corner geometry

• Parent material thickness

• Parent material strength

• Insert body dimensions

• Installation stroke or setting force

• Applied assembly torque

Full-hex geometry should not be interpreted as a universal guarantee of a particular torque rating.

Thin-Head Design Considerations

The thin-head configuration is intended to reduce flange protrusion.

This can help accommodate limited assembly clearances and closely positioned components.

However, reduced flange thickness or bearing area may affect resistance to push-through forces.

Where significant axial or bearing loads are expected, the head design should be evaluated against large-flange alternatives.

Closed-End Barrel Design

The closed-end barrel is a defining feature of this product.

Its enclosed rear section prevents the mating screw from passing through the bottom of the insert.

This can provide an additional physical barrier against contamination entering through the internal thread.

Screw-Length Selection

The available internal depth must be considered when choosing the mating screw.

A screw that is too long may bottom against the closed end before the intended joint clamping load is achieved.

This can produce misleading tightening resistance, insufficient clamp load or damage to the insert.

Engineers should verify:

• Available internal thread depth

• Screw engagement length

• Total joint thickness

• Washer and bracket thickness

• Required clamping conditions

• Rear barrel clearance

These dimensions must be confirmed using the approved product drawing.

Grip Range and Panel Thickness

The stated product-family grip range is 0.5–5.0 mm.

Actual compatibility depends on the selected insert configuration and parent material.

Thin panels require particular attention to deformation during installation.

Where the application involves multiple stacked sheets, the installation design should account for the effective grip thickness and required joint behavior.

Mounting-Hole Preparation

Full-hex rivet nuts require a mounting hole compatible with the hexagonal body.

Important dimensions include:

Oversized holes may reduce anti-rotation performance.

Undersized or distorted holes may prevent proper insertion or damage the rivet nut.

Hole preparation may involve punching, machining or other suitable processes, depending on the workpiece and production method.

Installation Process

Step 1 – Confirm Product Selection

Verify thread size, grip range, barrel length, flange geometry and closed-end clearance.

Step 2 – Prepare the Hexagonal Hole

Produce the required hole geometry according to the approved drawing.

Step 3 – Inspect the Parent Material

Check thickness, burr condition, hole geometry and surrounding panel flatness.

Step 4 – Select the Installation Equipment

Use suitable manual, pneumatic, hydraulic or automated setting equipment compatible with the selected insert.

Step 5 – Position the Insert

Place the rivet nut perpendicular to the mounting surface and confirm correct flange seating.

Step 6 – Apply the Setting Operation

Use the validated installation stroke or force to deform the insert body behind the panel.

Step 7 – Inspect the Installed Insert

Confirm flange seating, thread integrity, backside deformation and installation alignment.

Step 8 – Install the Mating Screw

Use an approved screw length and tightening procedure to avoid bottoming against the closed end.

Mechanical Performance Requirements

Spin-Out Torque

Measures the torque at which the installed insert begins to rotate relative to the parent material.

Axial Pull-Out Resistance

Evaluates the force required to extract the installed rivet nut from the workpiece.

Push-Out Resistance

Evaluates resistance to displacement under an applied axial force in the relevant direction.

Thread Integrity

Confirms that the internal thread remains functional after the installation process.

Installation Repeatability

Evaluates whether the setting process produces consistent results across representative production samples.

Joint-Level Performance

For critical assemblies, the complete joint should be evaluated rather than relying exclusively on the rivet nut specification.

The mating screw, panel geometry, clamp load and service environment all influence reliability.

Surface Treatment and Corrosion Considerations

The standard product described here has a blue zinc surface finish.

For engineering procurement, the coating specification should identify:

• Zinc coating thickness

• Passivation chemistry

• Corrosion-resistance requirements

• Surface appearance

• Restricted-substance compliance

• Inspection requirements

ISO 2081 and ASTM B633 may be relevant references where specified by the customer.

RoHS compliance should be supported by appropriate documentation for the supplied coating system.

Blue zinc appearance alone does not establish a specific salt-spray rating.

Closed-End vs Open-End Full Hex Rivet Nuts

Closed-end inserts should be selected when their enclosed barrel provides a useful application benefit.

For applications requiring complete environmental sealing, additional sealing design and testing may be necessary.

Custom Manufacturing and OEM Engineering Support

JUXIN FASTENERS can review drawing-defined requirements for:

• Special metric and imperial threads

• Custom full-hex body geometry

• Modified barrel lengths

• Special closed-end depths

• Alternative flange dimensions

• Custom grip ranges

• Alternative surface finishes

• Application-specific inspection requirements

• Customer-defined packaging

Manufacturing feasibility, minimum order quantities and lead times depend on the final specification.

Technical Documentation

Detailed dimensions should be confirmed using the corresponding product specification PDF and available CAD drawings.

Typical Industrial Applications

Electrical Cabinets and Switchgear

Closed-end hexagonal rivet nuts can be considered for removable covers, internal brackets and equipment mounting points in electrical enclosures.

Their enclosed barrel helps reduce the direct passage of contaminants through the threaded insert.

Telecommunications and Data Infrastructure

Communication cabinets and equipment racks often use thin sheet metal panels with limited rear access.

Thin-head full-hex inserts can provide serviceable threaded connections for internal support brackets, mounting plates and removable panels.

Industrial Automation

Industrial machinery housings, control panels and instrument brackets may benefit from anti-rotation threaded inserts that can be installed from one side.

HVAC and Thermal Equipment

Closed-end inserts may be evaluated for selected sheet metal equipment assemblies where threaded access points and contamination management are important.

Automotive Equipment

These rivet nuts may be considered for appropriate non-safety-critical sheet metal fastening applications, subject to customer design and qualification requirements.

Structural, crash-related or safety-critical applications require additional validation.

Why Choose a Closed-End Full Hex Rivet Nut?

This design is particularly useful when an OEM assembly requires:

• A mechanically retained internal thread

• Resistance to insert rotation

• Limited surface protrusion

• One-sided installation

• An enclosed rear barrel

• Repeatable assembly and maintenance access

The combination of these features can reduce the need for separate backside nuts and simplify selected sheet metal assembly operations.

Final product selection should be based on the actual installation geometry, mechanical loading, environmental exposure and customer drawing.
