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.

The effective protection against self loosening and unscrewing. The "SK" Serrated Locking Washer prevents self-loosening of screwed joints. 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. shape S (small) shape M (middle) shape B (wide) shape Z (for screws with cylindrical head shape) shape K (for electrical contacts)

The contact lock washer to NFE 25-511 and SN 70093 with grooved surface provides the designer the ability to secure wobble-prone screw effectively. It is particularly suitable for use on slot fasteners, dynamic cross-loaded to the screw connections and applications that require high biasing forces. Operational: The contact wheel ensures positively spring and a form-fitting locking. Form S = narrow - for small headrests Form M = average - for normal headrests Form B = wide - for large pressure transmission surfaces and slot fasteners Form K = serrated - for electrically conductive connections with contact teeth (SN 70093)
