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.
