    Dowel Pins

    Precisely align machine parts and prevent movement during assembly. These dowel pins are machined to tight tolerances and have a uniform diameter for a snug fit. They can also be used as a pivot, shaft, or hinge to join moving components. Since dowel pins can be hard to remove, they are best suited for permanent fixtures that don't require frequent adjustments or disassembly.

    High-Strength Alloy Steel—Our strongest, most wear-resistant pins, these won't bend or break from vibration. Use them for high-stress applications, such as mounting and aligning hydraulic cylinders and injection molds. They perform best in dry environments since moisture will cause them to rust.

    Pull-Out Dowel Pins

    Remove pins even when you only have access to one end or they sit flush with the surface of your part. With one internally threaded end, they are easier to remove than most dowel pins. Thread a screw into the pin and then pull with the removal tool (sold separately). You can also pull the screw with pliers, but there’s more risk of damaging the hole.

    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.

    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.

    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.
