Slotted Nut

Slotted Nut

A slotted nut is a type of nut that has slots cut into one end. The slots are designed to align with holes in a mating bolt or stud, allowing the insertion of a cotter pin for secure locking. The slotted nut and cotter pin combination is a simple yet highly effective way to ensure that a nut stays in place under conditions where it might be prone to loosening. It’s a tried and true method that has been used in many fields for decades.
