Headless Clevis Pins with Retaining Ring Grooves

Install or remove these pins from either side. Slide the included retaining rings into the grooves for a secure hold that takes up less space than a cotter pin. Replacement retaining rings are sold separately.
Zinc-plated steel pins have good strength and some corrosion resistance.
18-8 stainless steel pins offer a balance of strength and corrosion resistance. They may be mildly magnetic.

Ring-Grip Quick-Release Pins

The smooth ring handle on these pins won't catch on parts. A spring-loaded, nonlocking retaining ball pops out to hold pins in place. The hole should be as close to the diameter as possible, but not larger than the diameter at extended ball height. The ends are chamfered for easy insertion. Breaking strength is measured as single shear, which is the force required to break the pin into two pieces. Also known as faspins.
Zinc-plated steel pins have good strength and some corrosion resistance.
18-8 stainless steel pins offer a balance of strength and corrosion resistance. They may be mildly magnetic.
316 stainless steel pins have the best corrosion resistance of our stainless steel pins, and are as strong as 18-8 stainless steel pins. They may be mildly magnetic.

Flat-Head Quick-Release Pins

These pins have a low-profile head, so they won't get knocked out of place. Pins have a spring-loaded ball that pops out when the pin is pushed into a hole, and retracts when the pin is pulled out. For the best fit, the hole should be as close to the diameter as possible, but not larger than the diameter at extended ball height.
Zinc-plated steel pins have good strength and some corrosion resistance.
