Slotted Nuts

Slotted nuts, also known as castellated nuts, have grooved heads that align with holes in the mated bolt to accept the insertion of a cotter pin, locking the nut in place. They are commonly used to ensure that shaft components in certain automotive assemblies do not separate or to maintain machine settings in manufacturing environments.
