Thin Head Full Hex Steel Rivet Nuts – Open End, Color Zinc

Product Specifications – Thin Head Full Hex Steel Blind Rivet Nuts, Color Zinc

Product Overview

JUXIN FASTENERS offers thin-head full hexagonal steel blind rivet nuts with an open-end configuration and color zinc surface finish for industrial sheet metal fastening applications.

The full hexagonal body is designed to engage with a matching hexagonal mounting hole, providing mechanical resistance to rotation during screw tightening and removal.

The reduced-height head helps minimize surface protrusion, making these internally threaded inserts suitable for compact equipment housings,

 electrical cabinets, industrial machinery panels and other OEM sheet metal assemblies.

Standard Product Specifications

Important: The stated grip range represents the overall product family. Individual thread sizes may have different grip ranges, 

barrel lengths, head dimensions and installation-hole requirements.

Available Metric Thread Sizes

Thread pitches listed above are standard metric coarse-thread references based on ISO metric thread conventions. 

Final thread specifications must follow the approved product drawing.

Head and Body Geometry

Thin-Head Configuration

The reduced-height flange minimizes protrusion above the installation surface compared with conventional large-flange rivet nuts.

This feature is useful for equipment requiring compact assembly clearances.

However, the thin-head design must be evaluated against the required bearing area and push-through resistance.

Full Hexagonal Body

The full hexagonal body engages with a matching hexagonal hole to resist insert rotation.

This feature is particularly valuable in applications involving:

• Repeated maintenance and screw removal

• Sheet metal enclosures

• Removable machine covers

• Industrial equipment brackets

• Electrical and communication cabinets

Open-End Construction

The open-end configuration allows a mating screw to pass through the insert, subject to available rear clearance.

For applications requiring protection against moisture, dust or other contaminants, closed-end inserts or appropriate sealing arrangements should be considered.

Installation Hole Requirements

Correct hole preparation is essential for full-hex rivet nut performance.

Engineers should verify the following dimensions against the approved drawing:

Oversized mounting holes can reduce anti-rotation performance, while undersized holes can cause installation damage.

Material and Surface Finish

Steel Construction

Steel blind rivet nuts are commonly selected for industrial applications requiring mechanically retained internal threads in thin sheet metal.

Material properties must be selected according to the customer's mechanical loading and installation requirements.

Color Zinc Surface Treatment

Color zinc plating provides a plated protective surface with a colored appearance.

OEM coating specifications should identify:

• Required zinc coating thickness

• Passivation type

• Corrosion-resistance requirements

• Surface appearance

• Applicable restricted-substance requirements

• Inspection and acceptance criteria

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

The exact coating specification and compliance documentation must be confirmed for the ordered product.

Mechanical Performance and Validation

Full-hex rivet nut performance should be evaluated after installation in the actual parent material.

Spin-Out Torque

Measures resistance to rotation after installation.

Axial Pull-Out Resistance

Evaluates the force required to extract the installed insert from the parent material.

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 setting.

Installation Repeatability

Evaluates the consistency of installed geometry and mechanical retention across production samples.

Performance acceptance limits should be established using customer drawings, application requirements and representative testing.

Custom Manufacturing and OEM Requirements

JUXIN FASTENERS supports the review of custom blind threaded insert requirements, including:

• Special thread sizes and pitches

• Modified hexagonal body dimensions

• Alternative barrel lengths

• Reduced or modified flange geometry

• Special grip ranges

• Alternative surface treatments

• Custom inspection requirements

• Drawing-defined components

• Customer-specific packaging

Technical Specifications

The stated grip range covers the product family. Individual size-specific grip ranges and dimensional tolerances must be confirmed against the applicable technical drawing.

Why Choose Full-Hex Rivet Nuts Instead of Round-Body Inserts?

The choice between full-hex and round-body rivet nuts affects hole preparation, resistance to rotation and manufacturing processes.

Full-hex inserts are particularly useful when the application requires a strong mechanical interface between the insert body and the parent material.

A matching hexagonal mounting hole helps prevent the insert from rotating under tightening torque.

Round-body rivet nuts, by comparison, can be installed in conventional round holes and may be more convenient where shaped-hole production is unavailable.

The best option depends on the application.

Full-Hex Rivet Nuts

Advantages to evaluate:

• Geometric anti-rotation engagement

• Suitability for repeated screw removal

• Compatibility with one-sided installation

• Availability in low-profile head configurations

Engineering considerations:

• Requires matching hexagonal hole geometry

• Installation must be validated for the panel material

• Performance depends on correct setting conditions

Half-Hex Rivet Nuts

Half-hex rivet nuts use a partial hexagonal section and may offer a useful alternative depending on the body design and assembly requirements.

The two configurations should be compared using actual product drawings and application testing rather than assumed universal strength rankings.

Round-Body Rivet Nuts

Round-body inserts can be useful where conventional drilling or round-hole punching is preferred.

Knurled round-body designs may provide improved frictional resistance to rotation, but their installed performance depends on the panel material and hole condition.

Engineering Design Considerations

1. Hexagonal Mounting-Hole Preparation

The mounting hole must match the selected full-hex insert.

Important dimensions include:

• Across-flats measurement

• Corner geometry

• Hole tolerance

• Panel thickness

• Burr condition

• Edge distance

• Surface condition

Oversized holes may reduce anti-rotation performance.

Undersized holes may prevent correct seating or damage the insert.

The approved product drawing should define the required hole dimensions.

2. Grip Range and Panel Thickness

The stated family grip range is 0.5–6.0 mm.

Engineers must select a rivet nut configuration suitable for the actual sheet thickness.

For multilayer applications, the relevant thickness and clamping arrangement should be checked against the installation design.

3. Installation Stroke and Setting Force

Correct installation requires controlled deformation of the insert body.

Insufficient setting may reduce mechanical retention.

Excessive setting may damage the internal thread, deform the flange or affect the parent material.

Installation parameters should be established using representative production components.

4. Spin-Out Torque

Spin-out torque is the rotational load at which an installed insert begins to rotate relative to the parent material.

Full-hex geometry can improve resistance to rotation through mechanical engagement.

However, performance must be validated for the specific insert, panel material and hole geometry.

5. Axial Pull-Out Resistance

Pull-out resistance depends on the installed backside deformation, grip length, parent material and flange configuration.

Full-hex geometry alone does not establish an axial load rating.

Where significant mechanical loads are expected, representative testing should be included in the design approval process.

6. Thin-Head Bearing Performance

The thin-head design offers reduced surface protrusion, but it may provide less bearing area or head thickness than a large-flange alternative.

Applications involving significant push-through loads should be reviewed carefully.

7. Thread Engagement

Because the insert has an open end, mating screw length must be evaluated together with available rear clearance.

The selected screw should provide suitable engagement without interfering with components behind the panel.

Industrial Applications

Electrical Cabinets and Control Panels

Full-hex blind rivet nuts can provide threaded mounting points for removable sheet metal panels and internal brackets.

Typical applications include:

• Control cabinet covers

• Switchgear enclosure components

• Distribution equipment housings

• Internal mounting brackets

• Removable inspection panels

The anti-rotation body design is valuable where maintenance requires repeated screw removal.

For grounding or protective bonding applications, electrical continuity must be separately verified.

Telecommunications Cabinets

Communication equipment manufacturers frequently use thin metal panels and enclosed structures.

Thin-head full-hex rivet nuts can be considered for mounting equipment covers, support brackets and serviceable panels.

The low-profile head can help accommodate compact assembly layouts.

Industrial Automation Equipment

Potential applications include automation equipment housings, machine panels, instrument brackets and removable service covers.

One-sided installation can simplify assembly where rear access is restricted.

Automotive Components

Full-hex rivet nuts may be evaluated for selected non-safety-critical automotive sheet metal applications, including interior equipment brackets and removable accessory panels.

Applications involving structural loads, crash performance or vehicle safety require separate engineering qualification.

HVAC and Thermal Equipment

Fabricated sheet metal equipment may require threaded fastening points for removable covers, brackets and service panels.

The coating specification should be selected according to the actual temperature, humidity and corrosion environment.

Industrial Electronics and Equipment Housings

Electronic equipment manufacturers may use full-hex rivet nuts for internal support brackets, removable panels and mechanically fastened enclosures.

The selected insert must be compatible with the housing material, available clearance and required service life.

Color Zinc vs Blue Zinc: What Should OEM Buyers Specify?

Color zinc and blue zinc describe surface appearance, but appearance alone does not establish coating composition, thickness or performance.

Color zinc finishes are commonly associated with colored passivation systems. However, the exact chemistry and compliance status must be confirmed.

Blue or clear zinc finishes may use different passivation systems.

For OEM purchasing, the coating specification should address:

• Zinc coating thickness

• Passivation chemistry

• Required corrosion resistance

• Restricted-substance compliance

• Surface appearance

• Dimensional effects

• Batch-to-batch consistency

Relevant references may include ISO 2081 and ASTM B633, depending on the customer's specification.

A color zinc finish should not automatically be described as RoHS-compliant without supporting documentation.

Likewise, a blue zinc finish should not be assumed to have superior or inferior corrosion resistance based only on color.

Installation Recommendations

Step 1: Confirm the Drawing

Verify the insert thread size, body dimensions, flange configuration and grip range.

Step 2: Prepare the Mounting Hole

Produce the required hexagonal hole using a suitable manufacturing process.

Depending on the application, this may involve punching, machining, laser cutting or dedicated hole-forming equipment.

Step 3: Inspect the Hole

Confirm dimensional accuracy, burr condition and panel flatness.

Step 4: Select the Setting Tool

Use an appropriate manual, pneumatic, hydraulic or automated rivet nut installation system.

Step 5: Install the Insert

Position the insert perpendicular to the workpiece and confirm that the flange seats correctly.

Step 6: Set the Rivet Nut

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

Step 7: Verify Installation Quality

Inspect seating, thread integrity and backside deformation.

Where required, perform spin-out, pull-out and push-out testing.

Step 8: Assemble the Mating Screw

Install the mating screw using the approved tightening procedure.

Avoid excessive torque that could damage the installed insert or surrounding panel.

OEM Quality and Application Validation

For industrial production, a suitable inspection and validation plan may include:

Dimensional Inspection: Confirm thread dimensions, body geometry, flange dimensions and overall length.

Coating Verification: Confirm surface treatment requirements and applicable compliance documentation.

Mounting-Hole Compatibility: Verify that the insert fits the approved hexagonal hole.

Spin-Out Testing: Evaluate resistance to rotation under representative assembly conditions.

Pull-Out Testing: Evaluate axial retention in the actual parent material.

Thread Function Testing: Confirm that the internal thread remains functional after installation.
