Castle Nuts
A castle nut has a hex base and a crown cut with slots. A split pin passes through a cross-hole in the bolt and the slots, so the nut cannot back off. Used where a positive mechanical lock is needed, such as axles and steering joints.
- Split-pin locking
- Taller crown with slots
- Positive lock, no prevailing torque
