General:
Serrated Washers which are called nord lock washers fitted internally to the equipment and before a lock nut act as an anti-vibration device to prevent the cable gland or other cable entry device and lock nut. Particularly required in situation where vibrating heavy machinery such as mud, shakers, vibrating machine or pump, drilling equipment. Serrated lock washers increase the friction between the bolt head/nut and the mating surface. They do this by gripping into the mating surfaces. Serrated lock washers are installed between the bolt head/nut and the mating surface. The bolted joint is then tightened in the same way as an unsecured bolt. If the bolted joint experiences a loss of tension, the washer is no longer effective and must be replaced. Single part serrated washers can damage painted/coated surfaces because they have a tendency to rotate with the fastener. This risks damaging the surface, cracking the paint/coating and causing corrosion.d1 | used for | d2 | s |
