CASTLE NUT D935 20MM A4

Quantity:

A castle nut is a hexagonal nut with slots cut into one end, resembling the turrets of a castle. It is used with a drilled bolt or stud and secured with a split pin (cotter pin) passed through the slots and hole to prevent loosening. This locking method makes castle nuts ideal for critical assemblies where vibration resistance and safety are essential.
