    Bent-Head Clevis Pins

    Image of Product. Front orientation. Contains Annotated. Clevis Pins. Bent-Head Clevis Pins.
    Slightly curved, these pins take up less space than a loop grip or T-handle while still giving you something to grab. The bent head also acts as a stop so the pin can’t be pulled out from the other end. To secure, slide a cotter pin into the hole.
    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.

    Selectable-Length Bent-Head Clevis Pins

    Change the usable length in 1/4" increments by inserting a cotter pin into one of the holes. These pins are often used as replacement parts when you don't have the exact pin you need on hand. The bent head gives you a better grip than flat-head pins and acts as a stop so the pin can’t be pulled out from the other end.
    The excess length can be cut off after installation.

    Fasten coupling pins, base plates, guardrail posts, and other components to scaffold frames. They replace missing pins on your scaffold frame to help you comply with OSHA safety requirements. Made of galvanized steel, they resist rust and hold up to outdoor use.
    Pig Tail Pin—Pig-tail pins have a curved arm that wraps around the frame. They’re also known as gravity pins.
    Toggle Pin—Toggle pins have a hinged arm that flips down against the frame to lock the pin in place. They’re also known as hinge pins.
    Cal/OSHA Compliant Title 8 Section 1646 and OSHA Compliant 29 CFR 1926.451—Pins meet OSHA and Cal/OSHA dimensional and construction standards. Check local, state, and federal codes, including OSHA, for safe set up and operating practices.
