Castle Nuts

Castle nuts are often used with a bolt or threaded rod that has a predrilled hole, where a cotter pin can be used to secure the fixing and prevent movement.

Also known as castellated nuts, these are ideal for use in applications where vibration may undo the fixing.

They can also be referred to as slotted nuts, however, castle nuts are actually different fasteners altogether. Castle nuts look more like a hex nut with protruding triangular portions, whereas the slotted nut looks as though a hex nut has been cut with the slots and corners forming part of the protrusion.

This is a slotted nut.

Castle nuts are generally manufactured in steel or stainless steel, with other materials also available.

They are also available in a range of sizes, with specials available to order, and thin versions also available.
