    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.

    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.

    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.

    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.
