Slotted/Castellated Nuts


Metric Slotted Hexagon and Castellated Hexagon Nuts are six sided internally threaded fasteners with slots on the top of them.

When the slots of the nut are aligned with the hole in the bolt a separate fastener is inserted through the slots and the hole that keep the nut locked in place. The separate fastener is normally a cotter pin but spring tension pins or a threaded screw with a nylon insert locknut can also be used.
