Slotted Nuts

A slotted nut has slots cut into one end of the nut.

When it is used in an application, a bolt or threaded bar generally has a pre-drilled hole so that when the slotted nut is threaded on and torqued to the required position, it can be then secured using a cotter pin or write to prevent rotation.

Slotted nuts are used in applications where vibration or motion might undo the locknut.

Both a castle nut and slotted nut look similar, and can often be used interchangeably because they have almost identical dimensions. However, they are different in that the protrusions on a slotted nut are from the base of the nut and include the corners, whereas a castle nut looks like a standard nut with triangular portions protruding, but not including the corners of the hex.
