Clevis Pins

The most commonly used clevis pins—just slide a cotter pin into the hole to secure parts. These pins have a flat, low-profile head to fit in tight spaces. They're less likely to get in the way than pins with a loop grip or T-handle but aren’t as easy to grab if you want to remove them frequently. Add your own cotter pin, or choose a clevis pin that includes a reusable hairpin cotter.

Cotter Pin Not

Included

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.

Corrosion-Resistant Stainless Steel

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.

Clevis Pins with Retaining Ring Groove

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.

Headless Clevis Pins with Retaining Ring Grooves

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.

Loop-Grip Clevis Pins with Toggle

For components you need to lock in place but also disconnect frequently, these pins have a toggle end and large loop handle. No need for a separate cotter pin, the toggle swivels so you can insert into a hole and then swivels back to secure. Fold down the handle to save space when installed.

Ring-Grip Clevis Pins with Toggle

Attach a lanyard or tags to the split ring on these pins, and then lock them in place with the toggle. As you push the pin into a hole, the toggle swivels so you can insert and then swivels back to secure—no need for a separate cotter pin. The ring folds down out of the way to save space when installed.
