Knob-Grip Locking Quick-Release Pins

The tall, narrow head fits in tight spaces while still giving you something to grab. These pins have two retaining balls that lock them in place—push the button to insert and remove.

Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.

Secure the split ring to a lanyard to keep pins from getting lost, or attach tags to identify components.

High-Strength 17-4 PH Stainless Steel—The strongest stainless steel pins we offer, these are the least likely to deform due to stress and vibration. They resist rust in wet and outdoor environments but won't hold up to the harsh chemicals and acids that 316 stainless steel can.

Locking Quick-Release Pins for Tight Spaces

Slip into holes that are recessed, partially obstructed, or otherwise hard to reach. These pins are narrow with the smallest head of all our locking pins. They have two retaining balls that lock the pin in place—push the button to insert and remove.

Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.

Locking Quick-Release Pins with Recessed Button

Because the button doesn’t stick out, these pins won’t release accidentally if bumped. They have two retaining balls that lock the pin in place—push the button to insert and remove. The head has a hole for adding a split ring and a lanyard (sold separately). Also known as M-style marine pins.

Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.

Clamping Quick-Release Pins

The spring-loaded shaft draws thin sheets of material together and clamps them between the pin’s head and retaining balls. These pins are often used to secure sheet metal while welding to keep the sheets from sliding as you work. Press the button to extend the pin’s shaft and release to retract it up to 5 mm into the head.

Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.

Keep pins from getting lost when removed by securing the end of the attached lanyard to equipment.

18-8 Stainless Steel—The choice for wet and outdoor environments, these pins resist rusting. They are strong enough to join most components but won't withstand stress and vibration as well as steel.

Double-Locking Quick-Release Pins with Key

Limit who can remove these pins by requiring a key. Unlike double-locking pins with a cotter, you only need access to one side of these pins to remove them. Unlock and the button pops out so you can push it to release the retaining balls.

Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.

High-Strength Zinc Yellow-Chromate-Plated Alloy Steel—Our strongest, most wear-resistant pins. The durable zinc plating makes them suitable for wet and outdoor environments, but it won't hold up to the harsh chemicals that stainless steel can.

Quick-Release Pins for Blind Holes

Often used to position and hold parts during assembly and inspection, mate these pins with a receptacle to secure them in blind holes. Install the receptacle (sold separately) in the hole so you can insert the pin to join components. Three retaining balls lock pins in place until released.

Raised Push Button

With the narrowest head, these pins fit in tight spaces. Push the button to insert and remove.

Knob-Grip Quick-Release Pins

With a head that's tall and narrow, these pins fit in tighter spaces than a loop or T-handle while still giving you something to grab. The head also has a hole for adding a split ring and a lanyard (sold separately). A retaining ball holds pins in place until you pull to remove.

Breaking strength is measured as single shear, which is the force required to break the pin into two pieces.
