Clevis Pins

Clevis Pin

An alternative to bolts and rivets, these pins lock in place with a cotter pin. Choose a clevis pin and add your own cotter pin, or select a clevis pin that includes a reusable hairpin cotter pin.

Steel pins have good strength. Pins with a zinc-plated finish have some corrosion resistance.

Metric pins meet DIN 1444B specifications.

Precision Clevis Pins

These pins combine the locking capabilities of a clevis pin with the precision diameter of a dowel pin for a tight fit. Easier to install and remove than bolts or rivets, they lock in place with a cotter pin (sold separately).

18-8 stainless steel and black-oxide 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. They are as strong as 18-8 stainless steel pins and 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.
