Cotter Pins
Small part, big peace of mind. Our axle cotter pins keep your hardware right where it belongs — on the road. They help prevent nuts from backing off and pins from pulling out under vibration.
Family‑owned since 1962, Husky Trailer Parts Co. supplies the right size fast, so castle nuts and clevis pins stay secure mile after mile.
Find the Right Cotter Pin for Your Trailer Axle
Cotter pins are installed crosswise through a shank to keep components from sliding off or pins from pulling out — a simple, dependable mechanical stop. These standard pins are held by bending the tines outward after insertion for a secure hold.
What you'll find:
- 1/8" x 1-3/4" small cotter pins: Standard formed steel design for cross‑hole retention — insert and bend the tines to secure castle nuts or clevis pins.
- 1/4" x 3" large cotter pins: Zinc‑plated carbon steel for durable, corrosion‑resistant retention in heavier-duty applications.
It is essential to replace the axle cotter pin any time you service bearings. Never reuse removed or bent pins. If you're unsure which size you need, tell us your cross‑hole size and hardware, and we'll steer you to the right cotter pin — fast.
