Castle Nuts / Slotted Nuts

A castellated nut, sometimes referred to as a castle nut, is a nut with slots (notches) cut into one end. Castle Nuts are often used alongside a bolt or a threaded rod that feature a pre-drilled hole, where a cotter pin can be used to secure the fixing and prevent movement. These locknuts are also referred to as a ‘castellated nut’, and are ideal for use in applications where vibrations may undo a fixing.

Castle nuts are generally manufactured in steel or stainless steel, with other materials also available. They are available in a range of sizes – with specials available to order – and thin versions also available.

Castle nuts are used in conjunction with a cotter pin to prevent loosening. This nut has slots (notches) cut into one end. The name comes from the nut’s resemblance to the crenellated parapet of a medieval castle. The bolt or axle has one or two holes drilled through its threaded end. The nut is torqued properly and then, if the slot isn't aligned with the hole in the fastener, the nut is rotated to the nearest slot. The nut is then secured with a cotter pin or safety wire. Castellated nuts are used in low-torque applications, such as holding a wheel bearing in place.
