66-Piece Stainless Steel Cotter Pin Kit — Part 50-59438
A comprehensive assortment of stainless steel cotter pins in the most commonly used marine sizes. Cotter pins are a critical safety fastener — they lock clevis pins, castle nuts, and other fasteners in place, preventing loosening from vibration, wave action, and engine movement.
Stainless steel construction resists corrosion in salt and fresh water, making this kit a reliable addition to any onboard tool kit or service bench.
Parts Desk Insights
Best Use Case: An essential kit for anyone doing rigging work, steering system service, or trailer maintenance. Cotter pins are used throughout marine applications — securing clevis pins in standing rigging and turnbuckles, locking castle nuts on steering components and propeller shafts, and retaining pins on trailer hitches and safety chains. Having a full size range on hand means you’re never held up by a missing pin during a service job. Castle nuts are sold separately.
