What is castle nuts?
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.
product features
These components are used in combination with a screw that has a pre-drilled radial hole. The nut is attached and a pin is passed through the notches and the hole in the screw, preventing the nut from turning.
Several types of pins may also be used for this purpose. These include:
A cotter pin, also known as a split pin — a fastener with twin tines, which after insertion are bent apart to prevent removal.
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.
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.
Castellated nuts are often threaded with Unified inch fine (UNF) or Unified inch coarse series (UNC) with thread diameter — typically from 1/4 to 1-1/2-inch in varying nut widths and heights.
A castellated nut has a cylindrical top of a smaller diameter where the notches are, with a higher profile than a typical nut of its size. It’s similar to a slotted nut but the rounded section featured on a castellated nut allows the pin to be secured tighter to the nut than is possible with a slotted nut.
Applications
Additionally, a castellated nut is a locking device that’s resistant to movement and vibration but that can be readily removed. This makes it a popular choice for securing the position of a bearing onto a spindle. Castellated nuts are commonly used within the automotive, aircraft, and locomotive industries.
