SERRATED LOCK WASHER
NSK- S – NSK-M – NSK-B – NSK-E – NSK-K – NSK-L
Lock Washer
The effective protection against self loosening and unscrewing.
The “NSK” LOCK WASHER is the improved design of the “SK” LOCK WASHER.
It also prevents self-loosening of screwed joints and damage to the bearing surfaces and consequent variations in the tightening torques, as they occur in threadlockers with teeth are avoided with lock washers through the special geometrical shape of the locking edges even better than the proven “SK” LOCK WASHER.
NSK-S
NSK-S for small headrests
NSK-M
NSK-M for high-strength connections with normal head supports
NSK-B
NSK-B for large pressure transfer areas and slotted hole fastenings
NSK-E
NSK-E for Electrical contact joints
NSK-K
NSK-K with contact teeth for electrically conductive joints through painted surfaces
NSK-L
NSK-L for slotted hole fastenings with limited installation space
