The Nord Lock Washer is a washer consisting of two identical washers, which have radial notches on one side that create a force effect on the contact surfaces, and wedges on the other side that increase pre-tightening during vibration.
Scope AN 133 is used in construction and heavy engineering to prevent loosening of fasteners under high dynamic loads and vibration. Among all types of self-locking or locking fasteners, these washers provide the most effective results. Thanks to this, these washers were widely used in the constructions of railway transport, port cranes, wind generators, etc.
Material high-strength structural alloy steel.
Coating Zinc plated protects against corrosion if fasteners are intended to be used in aggressive environments.
