We’ve supplied quick release pins to aerospace MRO shops, motorsport teams, and OEM design engineers for years — and that experience shapes every pin we sell.

• Aerospace-grade materials: 17-4PH stainless steel (H1025/H1150 condition), 300-series stainless, and titanium options for corrosion resistance and strength.
• Tested shear strength: Each diameter is rated and documented, so engineers can spec with confidence.
• Wide size range: Pin diameters from 3/16″ to 1″ (and metric M5–M25), with grip lengths from 1/4″ up to 6″.
• In stock, fast ship: Most standard pins ship same day from our warehouse.
• Custom builds: Need a non-standard grip, lanyard, or handle? Our team manufactures to print.
• Compliance-ready: Material certs and traceability available on request.

How to Choose the Right Push Button Quick Release Pin

Picking the wrong pin can mean joint failure or premature wear. Use this short buying guide to spec correctly.

1. Measure the Grip Length

Grip length is the usable shaft between the head and the locking balls — not the full pin length. Measure the total thickness of the materials being joined and add a small clearance (typically 1/32″). Too much grip causes play; too little prevents the balls from locking.

2. Choose the Diameter for the Load

Match shaft diameter to your single shear or double shear load. Larger diameters carry more, but also need larger holes. As a rough guide:

• 3/16″ – 1/4″: light fixturing, panels, covers
• 5/16″ – 3/8″: jigs, machine guards, equipment latches
• 1/2″ – 3/4″: structural pinning, motorsport, rigging
• 1″+: heavy industrial, towing, aerospace ground support

Always check the published shear rating before final selection.

3. Single Acting vs. Double Acting

• Single-acting pins: locking balls retract only when the button is pressed. Best for vertical or supported installations.
• Double-acting pins: balls retract on insertion and on button press — a safer choice when the pin could be unintentionally pushed out.

4. Pick the Right Handle Style

• T-handle: maximum grip and leverage
• L-handle: low-profile, snag-resistant
• Ring handle: lanyard-friendly, lightweight
• Button handle: flush-fit for tight spaces

5. Match the Material to the Environment

Use 17-4PH stainless for high-strength applications. Choose 300-series stainless for marine or chemical exposure. Specify titanium when weight is critical.

Push Button Quick Release Pin Applications

Our customers use these pins across demanding industries:

• Aerospace: panel fasteners, ground support equipment, tooling
• Motorsport: hood pins, body panels, seat mounts, jack stands
• Defense & military: weapon mounts, rapid-deploy gear
• Industrial OEM: machine guards, conveyors, tooling fixtures
• Marine: deck hardware, rigging, davits
• Agriculture: implement attachments, hitch pins
• Medical & lab: equipment carts, modular furniture

Materials & Features Explained

Locking ball mechanism: Hardened chrome steel or stainless balls retained by an internal plunger and spring. Pressing the button retracts the plunger, freeing the balls to retract into the shaft.

Spring: Stainless steel for corrosion resistance and consistent release force over thousands of cycles.

Lanyards & accessories: Optional cable lanyards, split rings, and retention clips prevent loss in service.

Frequently Asked Questions

What is a push button quick release pin?

A push button quick release pin is a fastener with internal locking balls that lock against a mating hole. Pressing the button retracts the balls, allowing instant insertion or removal without tools.

What is the difference between single acting and double acting quick release pins?

Single-acting pins require the button to be pressed for both insertion and removal. Double-acting pins automatically retract the balls during insertion but still require a button press to release — adding a layer of safety against accidental disengagement.

How much weight can a push button quick release pin hold?

Load capacity depends on diameter, material, and shear plane. A 1/4″ 17-4PH pin typically holds several thousand pounds in double shear, while a 1″ pin can exceed 30,000 lbs. Always check the manufacturer’s published shear rating for your specific pin.

Are push button quick release pins reusable?

Yes. Quality pins are designed for thousands of insertion cycles. Inspect the locking balls and spring action periodically and replace any pin that shows wear, deformation, or weak release.

How do I measure grip length on a quick release pin?

Grip length is measured from the underside of the handle to the center of the locking balls — not the tip. It should match the total thickness of the materials you’re joining, plus a small clearance.

Can push button quick release pins be used in saltwater or marine environments?

Yes, when specified in 300-series stainless steel or titanium. These materials resist saltwater corrosion. Avoid carbon steel pins in marine use, and rinse pins after exposure to extend service life.

Do you offer custom push button quick release pins?

Yes. We manufacture custom diameters, grip lengths, handle styles, materials, and lanyard configurations to print. Contact our engineering team with your drawing or specs for a quote.
