    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.

    Flat-Head Quick-Release Pins

    With no ring or handle to get caught on nearby components, these pins won’t pull out accidentally. The low profile makes them similar to basic clevis pins. Although the thin head fits in cramped spots, it also makes the pin harder to grab. A retaining ball holds pins in place once installed—pull to remove.
