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


Carbon Steel	Zinc-Plated Carbon Steel

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—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.

Tethered Loop-Grip Clevis Pins

Lock and release components again and again without losing your cotter or linch pin. These clevis pins have a lanyard or chain that keeps your securing pin attached. The loop handle is large enough for multiple fingers, so you can get the leverage you need to easily grip and pull it. They’re often used for towing and other applications that require frequent pin removal.

Steel

With Cotter Pin and Lanyard

Painted Carbon Steel—Stronger than stainless steel, these pins won't deform from stress and vibration. The dark enamel creates a finished look but offers minimal corrosion resistance. They're best for dry environments.

Cotter Pin Included—The hairpin cotter is quicker to install and remove than a linch pin but not as secure.

Plastic-Coated Handle—Prevents your grip from slipping on the handle.

Clevis Pins with Locking Retainer

Secure and release these heavy duty pins with one hand. Swing the welded solid steel retainer closed, and it locks onto the pin until you press the lever to open. Unlike other clevis pins, you don’t have to reach around to insert a cotter pin or worry about it falling out. These are often used for towing since they make it easy to hitch and unhitch your equipment.

Steel

Powder-Coated Carbon Steel—A shiny black finish creates a barrier against rust in damp and outdoor environments. While not as corrosion resistant as stainless steel, these pins are stronger and won't deform under stress.

Loop-Grip Clevis Pins

Easily grip and pull these pins to quickly release components. The loop handle is large enough for multiple fingers to give you more leverage than you can get with standard clevis pins. These pins are often used for towing and other applications that require frequent pin removal.
