Self-locking nut 12 mm AZI, 6 pieces.

The lock nut is a nut that is designed to prevent the accidental loosening of screws. It will, as the name suggests, brake the screw and hold it securely.

Its main function is to prevent unscrewing, thanks to its nylon ring. The lock nut is shock and vibration resistant and will not unscrew. The nut is a time-tested, controlled tightening method that ensures a long service life.

Locknuts are used where there is a risk of vibration. When the screw is screwed into the nut, the thread is created in the nylon ring and holds it firmly in place, thus ensuring effective resistance. This phenomenon has an impact on the tightening torque.

The stainless steel locknuts have the particularity of not rusting. Stainless steel, A2 or A4, can be used both indoors and outdoors, and is an efficient material in all circumstances, which is also very watertight.
