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 stainless steel. The A4 steel grade allows you to use fasteners at significant temperature changes and in an aggressive and humid environment.
