FAQ
Q: Are cotter pins reusable?
A: Traditional cotter pins (split pins) are single-use — once bent to lock, they should be replaced with a new pin after removal. For reusable retention, consider R type spring cotter pins instead.
Q: What size cotter pin do I need?
A: The cotter pin diameter should be slightly smaller than the hole in the shaft or clevis pin. The pin length should be long enough for the legs to be bent back after insertion.
