On castle nuts, the turret end is turned down enabling the lock pin to be wound against the turret.

Lock the nut to a mated bolt by using a pin or wire threaded through the bolt and slots on the nut.

18-8 stainless steel is functionally interchangeable with type 304 stainless steel.

Stainless steel significantly improves resistance to tarnishing or corrosion.
