High-Visibility Loop-Grip Quick-Release Pins

A bright orange handle makes these pins stand out. Good for components you need to disconnect frequently, the loop is easy to grip—even with gloves or slippery hands. Pins have a retaining ball that holds them in place until you pull to remove.

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.

Steel

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

A lanyard or chain prevents your pin from getting lost when removed. With a large loop handle that's easy to grip and pull, these clevis pins are often used for towing and other applications where you regularly secure and release components.

Steel

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.

Zinc-Yellow-Chromate-Plated Carbon Steel—With a more durable finish than clear zinc plating, these pins hold up in wet and outdoor environments although not as well as stainless steel. Because the plating resists wear and the steel holds up under stress, they're good for pivoting parts, like rod end linkages.

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

Linch Pin Included—Less likely to get knocked or shaken out of place than a hairpin, the linch pin has a ring that snaps down and locks.

Corrosion-Resistant Stainless Steel


With Cotter Pin and Lanyard	With Linch Pin and Chain

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.

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

Linch Pin Included—Less likely to get knocked or shaken out of place than a hairpin, the linch pin has a ring that snaps down and locks.
