Product Description

Product Description

A castellated nut, also known as a castle nut, has three notches in one end, giving an appearance similar to the crenellated battlements of a castle. Castellated nuts are a positive locking device that's used to ensure that the nut remains affixed and resists vibration.

Several types of pins may also be used for this purpose. These include:
1. A cotter pin, also known as a split pin - a fastener with twin tines, which after insertion are bent apart to prevent removal.
2. An R-clip, also known as a hairpin cotter pin or hitch pin - a sprung metal fastener with one straight leg inserted into the hole and one profiled leg that grips the outside of the nut.
3. Safety or locking-wire - a wire that's passed through the notches and the hole, then twisted, and anchored to secure the nut.  

With six notches spaced at 60-degree intervals, the castellated nut can only be locked where a notch corresponds to the hole. After correct torquing, it's necessary to turn the nut again up to 30 degrees (in either direction) to locate the hole. 

As fine-tuning the torque is not possible, castellated nuts are better suited to low-torque applications. They're unsuited to applications that require a specific preload.
