1 1/2" Pins | McMaster-Carr

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

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

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

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.

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.

High-Strength Anchors for Concrete

Offering the highest pull-out strengths, adhesive grips the anchors' lobes and knurls to keep anchors from shaking loose. These anchors are often used to secure heavy machinery with jarring starts and stops, such as compressors and compactors.

To install, fill a clean, drilled hole half full of epoxy adhesive (sold separately). Thread a screw or threaded rod into the anchor and then slightly twist the anchor into the hole until it's flush with the surface. Then, hammer the head of the screw or rod a few times for a snug fit. All create a permanent female-threaded connection that lets you remove and reinstall a screw or threaded rod.

Zinc-Plated Steel—The most common choice for areas with occasional exposure to moisture.

Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these anchors won't degrade when exposed to harsh weather, salt water, and most chemicals.
