    Clevis Pins with Retaining Ring Groove
    3D CAD models available

    Insert the retaining ring into the groove for a secure hold that takes up less space than a cotter pin. The ring surrounds the entire pin, so bumps are unlikely to work these pins out of a hole.
    Unlike most cotter pins, which install by hand, you will need retaining ring pliers to insert and remove the included ring.

    Zinc-Plated Carbon Steel—These pins withstand occasional exposure to moisture. However, since friction from moving parts can wear away the finish, they're not ideal for wet environments. While not nearly as corrosion resistant as stainless steel, they are stronger and won’t deform under stress.

    18-8 Stainless Steel—The choice for wet and outdoor environments, these pins resist rusting. They're strong enough to fasten most components but won't withstand stress and vibration as well as steel.
    316 Stainless Steel—Our most corrosion-resistant pins, these hold up in just about any environment. They won't degrade from exposure to weather, salt water, and most chemicals. Like 18-8 stainless steel, they're strong enough to fasten most components but won't withstand stress and vibration as well as steel.

    Headless Clevis Pins with Retaining Ring Grooves
    3D CAD models available

    Secured with a retaining ring at either end, you can add and remove parts without having to take the pin all the way out. These pins are commonly used with rod ends, hydraulic cylinders, and other pivoting components. In addition to taking up less space than cotter pins, the retaining rings surround the entire pin, so bumps are unlikely to work it loose.
    Unlike most cotter pins, which install by hand, you will need retaining ring pliers to insert and remove the included rings.

    Zinc-Plated Carbon Steel—These pins withstand occasional exposure to moisture. However, since friction from moving parts can wear away the finish, they're not ideal for wet environments. While not nearly as corrosion resistant as stainless steel, they are stronger and won’t deform under stress.
