Parts Desk Insights
Best Use Case: Use this cotter pin where a split-pin retaining fastener is needed to prevent a nut, bolt, or linkage from backing out—pass the pin through the drilled hole, then spread the ends to lock.
Common Issues: If the pin doesn’t seat easily, confirm the hole size in the mating part (pin diameter is 3/32"). Also double-check length (3/4") so the legs have enough room to spread and lock securely without contacting nearby components.
