Aluminum Locking-Collar Rivets

Aluminum Locking-Collar Rivets and Ring-Groove Lockbolts for Lightweight OEM Assemblies

Product Overview

JUXIN FASTENERS supplies aluminum locking-collar rivets, also known as aluminum lockbolts or aluminum ring-groove fastening systems, for industrial OEM manufacturing and lightweight metal assemblies.

JUXIN Product Reference: JX-D-L-AL

This product family uses a grooved aluminum pin and a compatible aluminum locking collar.

During installation, dedicated tooling draws the connected components together and swages the collar into the locking grooves of the pin.

The resulting connection provides permanent mechanical fastening through the engagement of the pin and collar.

Unlike conventional blind rivets, typical two-piece aluminum locking-collar rivets require access to both sides of the joined components.

Aluminum lockbolts may be evaluated where component weight, material compatibility, installation efficiency and mechanical joint performance are important.

The exact aluminum alloys, pin geometry, collar design, grip range, strength and installation tooling must be confirmed against the approved engineering specification.

Product Specifications

Product Components: Aluminum Pin and Locking Collar

An aluminum locking-collar fastening system consists of two separate engineered components.

1. Aluminum Lockbolt Pin

The pin passes through the aligned mounting holes of the joined components.

Depending on the selected design, the pin may include:

• Formed head

• Load-bearing shank

• Ring-groove locking section

• Grip section

• Installation gripping section

• Designed breakneck or other installation feature

The actual geometry must be verified from the approved drawing.

2. Aluminum Locking Collar

The collar is positioned over the pin on the opposite side of the joint.

During installation, the collar is plastically deformed into the pin grooves.

The collar material, hardness, dimensions and swaging characteristics must be compatible with the selected pin.

Pins and collars must be specified as matched fastening components.

Engineering Solution 1 — How Aluminum Locking-Collar Rivets Work

A two-piece aluminum lockbolt creates a permanent mechanical connection through collar swaging.

The typical installation sequence is:

1. Prepare the mounting holes.

2. Align the joined components.

3. Insert the aluminum pin through the joint.

4. Position the compatible aluminum collar on the opposite side.

5. Engage the approved installation tool.

6. Apply the required installation force.

7. Draw the connected components together.

8. Swage the collar into the pin grooves.

9. Complete the designated installation cycle.

10. Inspect the installed pin and collar.

For break-pintail designs, the installation tail breaks at the designated location.

For pintail-less systems, installation is completed without a conventional break-off tail.

These configurations require different engineering and tooling considerations.

Engineering Solution 2 — Why Select Aluminum Lockbolts?

Aluminum has a lower density than steel.

For suitable applications, aluminum fastening components may contribute to reduced assembly weight.

Potential benefits may include:

• Lower fastener mass

• Compatibility with selected aluminum structures

• Permanent mechanical fastening

• Efficient production installation

• Reduced use of threaded fastening components where appropriate

However, lower weight does not establish equivalent strength.

The mechanical performance of aluminum lockbolts must be evaluated against the actual application requirements.

Engineering Solution 3 — Aluminum vs. Steel Lockbolts

The selected material must satisfy the complete joint design rather than a simple weight comparison.

Engineering Solution 4 — Aluminum Alloy Selection

The original JUXIN product description mentions 7A03 aluminum alloy for the pin and 5052 aluminum alloy for the collar.

These exact material grades have not been independently verified against the approved product drawing or material certificates.

The engineering specification should establish:

• Pin aluminum alloy

• Collar aluminum alloy

• Material temper

• Mechanical properties

• Hardness

• Formability

• Corrosion resistance

• Surface finish

• Traceability

The pin and collar may require different material characteristics.

The pin must carry the specified mechanical loads, while the collar must deform correctly during installation and maintain engagement with the grooves.

Engineering Solution 5 — Ring-Groove Mechanical Locking

The ring-groove profile provides the mechanical interface between the pin and collar.

During installation, the collar material is forced into the grooves by the swaging tool.

Important parameters include:

• Pin groove diameter

• Groove profile

• Groove spacing

• Collar internal diameter

• Collar wall thickness

• Material hardness

• Swaging force

• Installed collar dimensions

A compatible pin-and-collar combination is essential.

Collars from different systems must not be assumed interchangeable.

Engineering Solution 6 — Shear Strength

Shear loading acts across the fastener and joint interface.

Aluminum lockbolt shear capacity depends on:

• Pin diameter

• Aluminum alloy

• Material temper

• Pin geometry

• Shear-plane location

• Joint thickness

• Hole diameter

• Installation quality

The complete joint must also be evaluated for panel bearing, edge tear-out and other failure mechanisms.

No numerical shear strength is claimed without verified product data.

Engineering Solution 7 — Tensile Strength

Tensile loading acts primarily along the fastener axis.

Potential failure mechanisms include:

• Pin fracture

• Collar deformation

• Collar disengagement

• Pin head pull-through

• Panel deformation

• Local material failure

The pin-and-collar connection must be qualified as a complete system.

No numerical tensile strength is claimed without verified product testing.

Engineering Solution 8 — Clamp Force and Joint Integrity

The installation process draws the joined components together while the collar is swaged into the pin grooves.

The resulting clamp behavior depends on the selected fastening system.

Relevant factors include:

• Joint thickness

• Material stiffness

• Surface condition

• Collar design

• Tooling condition

• Installation force

• Groove geometry

• Joint relaxation

No specific clamp force or preload value is claimed without supporting data.

Engineering Solution 9 — Vibration Resistance

Aluminum locking-collar systems may be considered for assemblies exposed to vibration and repeated mechanical loading.

However, vibration resistance depends on the complete joint.

Engineering validation should consider:

• Joint stiffness

• Clamp retention

• Collar engagement

• Cyclic loading

• Hole fit

• Fatigue

• Corrosion

• Installation quality

The term vibration-resistant should not be interpreted as a universal guarantee.

Engineering Solution 10 — Fatigue and Dynamic Loading

Fatigue performance is important in transportation equipment, industrial machinery and structural frames.

Relevant factors include:

• Applied load spectrum

• Pin diameter

• Aluminum alloy

• Material temper

• Joint geometry

• Fastener spacing

• Hole quality

• Clamp retention

• Environmental exposure

Representative joint testing is required where fatigue performance is critical.

Engineering Solution 11 — Galvanic Corrosion and Material Compatibility

Aluminum assemblies may contain fasteners and components made from different metals.

When dissimilar metals are electrically connected in the presence of an electrolyte, galvanic corrosion may occur.

Engineering considerations include:

• Pin alloy

• Collar alloy

• Mating panel material

• Surface coatings

• Moisture exposure

• Electrical contact

• Joint design

An aluminum pin-and-collar system does not automatically eliminate galvanic corrosion risk.

Material compatibility must be evaluated for the actual assembly.

Engineering Solution 12 — Aluminum Corrosion Resistance

Aluminum can develop a protective oxide layer under suitable conditions.

However, aluminum is not corrosion-proof.

Potential concerns include:

• Pitting corrosion

• Crevice corrosion

• Galvanic corrosion

• Chloride exposure

• Chemical exposure

• Surface contamination

No salt spray rating or corrosion service life is claimed without verified testing.

Engineering Solution 13 — Thermal Expansion and Contraction

Aluminum generally has a higher coefficient of thermal expansion than many steels.

Temperature changes can affect joint dimensions and loading.

Important considerations include:

• Pin alloy

• Collar alloy

• Mating material

• Operating temperature

• Temperature cycling

• Joint stiffness

• Clamp relaxation

The complete joint must be evaluated for the expected thermal environment.

Engineering Solution 14 — Grip Range and Pin Length

The selected pin must accommodate the combined thickness of the connected components and the required collar engagement.

Engineers should confirm:

• Minimum grip

• Maximum grip

• Pin length

• Collar thickness

• Locking groove engagement

• Installation tail geometry

• Tooling clearance

• Final pin projection

Incorrect grip selection may prevent complete collar swaging.

Engineering Solution 15 — Mounting-Hole Diameter and Joint Preparation

Hole dimensions affect mechanical performance and installation consistency.

Important parameters include:

• Hole diameter

• Hole tolerance

• Hole alignment

• Edge distance

• Fastener spacing

• Burr condition

• Surface cleanliness

• Joint gap

Oversized, cracked or damaged holes must not be accepted without engineering approval.

Engineering Solution 16 — Break-Pintail and Pintail-Less Designs

Not all ring-groove lockbolts use the same installation sequence.

Break-Pintail Lockbolts

These designs include an installation section that breaks at a designated location after the required installation sequence.

Pintail-Less Lockbolts

These designs complete collar swaging without a conventional break-off pintail.

Huck BobTail is a proprietary example of a pintail-less system.

The JUXIN JX-D-L-AL configuration must be checked against its actual drawing before assigning either design.

Engineering Solution 17 — Installation Tooling

Aluminum locking-collar rivets require compatible installation tooling.

Tool selection should consider:

• Pin diameter

• Collar diameter

• Pin geometry

• Required pulling force

• Swaging force

• Tool stroke

• Nose assembly

• Working clearance

• Production cycle time

• Tool maintenance

• Operator safety

The correct tool and nose assembly are essential for consistent installation.

A conventional blind-rivet tool should not be assumed suitable.

Typical Installation Procedure

1. Confirm the approved pin and collar part numbers.

2. Verify the aluminum alloy specifications.

3. Check the complete joint stack-up.

4. Select the correct grip range.

5. Prepare aligned mounting holes within approved tolerances.

6. Remove burrs and inspect the joint surfaces.

7. Insert the aluminum pin through the assembly.

8. Position the compatible collar on the opposite side.

9. Select the approved installation tool and nose assembly.

10. Engage the tool with the pin.

11. Activate the tool according to the approved procedure.

12. Allow the collar to be swaged into the locking grooves.

13. Complete the pintail break if required by the selected design.

14. Release the tool after the specified installation cycle.

15. Inspect the collar swage, pin projection and joint condition.

16. Verify installation against the approved acceptance criteria.

Pintail-less systems must follow their own installation procedures.

Engineering Solution 18 — Production Quality Control

For production managers and manufacturing engineers, repeatable aluminum lockbolt assembly requires controlled components, tooling and inspection.

Important quality-control items include:

• Approved pin part number

• Approved collar part number

• Aluminum alloy verification

• Material temper verification
