Locking nuts, also referred to as locknuts, prevailing torque nuts or self-locking nuts, are designed to remain securely fastened under conditions that would cause a normal nut to loosen. They usually operate by requiring prevailing torque during installation that generally comes in the form of deformed threads, inserts or serrated surfaces which bite into the mating bolt.
