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.

Steel

Cotter Pin Not

Included

Carbon Steel—Stronger than stainless steel, these pins won't deform from stress and vibration. They perform best in dry environments since moisture will cause them to rust.

Zinc-Plated Carbon Steel and Zinc-Yellow-Chromate-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

Cotter Pin Not

Included

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.

Black-Oxide 18-8 Stainless Steel—Typically chosen for their appearance, these pins have a dark, matte coating to create a finished look. Even if friction from moving parts wears away the finish, they won't rust in wet and outdoor environments. While these pins are strong enough to fasten most components, they don't withstand stress and vibration as well as steel.

Highly Corrosion-Resistant 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.

High-Strength 17-4 PH Stainless Steel—The strongest stainless steel pins we offer, these are the least likely to deform due to stress and vibration. Similar to 18-8 stainless steel, they're suitable for most wet and outdoor environments. However, they won't hold up to the harsh conditions and chemicals that 316 stainless steel can.
