CASTLE NUT

An embattled nut, every so often referred to as a castle nut. It is a nut with notches cut into one end. The name derives from the nut’s similarity to the crenelated bulwark of a primitive castle. Castel nuts are sometimes denoted erroneously as castigated nuts. A castle nut has three slashes in one end. Castel nuts are an optimistic locking fastener used to make sure that the nut remnants are affixed and battles vibration. Castel nuts are differentiated from other types of nuts by their usage of a pin. In addition to a bolt, they need a pin. After contracting a castle nut onto the end of a bolt, a pin is introduced through the center. The pin will hold the castle nut in place.

Castle Nuts are frequently used together with a bolt or a threaded rod that features a pre-drilled hole, where a cotter pin can be used to lock the fixing and avert 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 visually look more like a hex nut and host protruding triangular portions, whereas a slotted nut (pictured to the right), looks as though a hex nut has been cut with the slots and corners forming part of the protrusion. The structural individuality of these nuts enables them to be used in mechanical and automotive applications where positive locking is required, like holding a wheel bearing in place. These are also used as safety nuts for other component conniving applications.

Castle nuts from SEF arise with pre-drilled holes through which cotter pins can be inserted to hold the nuts firmly in place. It enables the nuts to endure constant ambiances and allows them to stay in place during small movements. As these nuts are pre-drilled, they can be used without a pilot hole. Castle nuts are positioned, letting them be installed and detached using screwdrivers. These are available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant.
