Washers Nord Lock

Main features

NORD LOCK is an anti-unscrewing tightening system composed of a pair of washers which have a series of cams on the internal side, with an angle of inclination and on the external side a radial knurling-serration.

This system allows you to tighten using tension rather than friction, thus allowing an assembly of the highest quality and safety.
Available in stainless steel or cadmium-plated steel.
