Locking nuts or lock nuts are special types of fastener designed to achieve a secure fixing. Some suppliers call them self-locking nuts or stiffnuts. They are screwed onto a bolt or threaded rod just like standard nuts, but a lock nut will then resist loosening under torque or vibration forces.

A flange nut is a nut that has a wide flange at one end that acts as an integrated washer. This serves to distribute the pressure of the nut over the part being secured, reducing the chance of damage to the part and making it less likely to loosen as a result of an uneven fastening surface. These nuts are mostly hexagonal in shape and are made up of hardened steel and often coated with zinc.

A nyloc nut, also referred to as a nylon-insert lock nut, polymer-insert lock nut, or elastic stop nut, is a kind of locknut with a nylon collar that increases friction on the screw thread
