Castle Nut Wrench | How to Install & Remove Castle Nuts?

Castle Nut

Castle Nut also named Castellated Nut, a nut with notches cut for one end. As the nuts resemble the crenelated parapet of a medieval castle, the name Castle Nut came up. Castle Nut sometimes wrongly called as castigated nuts.

These nuts often mentioned as slotted nuts but there will be a slight difference. There is a castle nut wrench to remove or install the nuts.

Castle Nuts designed in a way that requires a pin that fits through the slots and a hole in the screw for which the nut is attached. The pin used is a cotter pin that prevents the nut from loosening and turning.

Castellated nuts allow the cotter pin tightened closer to the margin of the nuts to provide secureness. Castle nuts are used for low-torque applications, as holding a wheel bearing in place.
