Product applications

Washers have found their wide application in the aircraft industry, automotive industry, construction, engineering and industrial sectors, as well as in many other areas. Lock washers are important fastening elements and are designed to lock nuts, as well as hexagonal bolts. Lock washers are very popular in critical connections, which are prone to loosening due to vibration or heavy loads. After installing the washer, the petals and foot of the product are bent in different directions, which securely fixes the washer relative to the nut or bolt and the entire connection relative to the element to be fixed.
