Slotted Nut and Castle Nut Manufacturers.
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.
SLOTTED NUT
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.
