Castle Nuts

Castle Nuts (Din 935) In Stock

Castle nuts, also known as castellated nuts, are used with a bolt or allthread that has a predrilled hole where a cotter pin can be used to secure the fixing, preventing movement. This makes them ideal for use in applications where vibration may undo the fixing.

Often also known as slotted nuts, castle nuts are slightly different, looking more like hex nuts with triangular portions protruding, whereas the slots on the slotted nut look as though they have been cut from a hex nut with the corners also forming part of the protrusion.

This is a slotted nut
