Nord-Lock X-Series wedge-locking washers

Bolted joints fail for two reasons - spontaneous bolt loosening and slackening. Nord-Lock multifunctional wedge-locking technology tackles both, offering you total security for those situations when there can be no compromise.

This product is the optimum choice when you have both vibrations and applications with risk of slackening, such as applications with short clamp length, multiple clamped parts, gaskets, soft metals, plastic composites, coatings and thermal cycling.

Nord-Lock X-series steel washer promises the highest corrosion resistance in the market, it is tested at least 1,000 hours in the Neutral Salt Spray Test (According to ISO 9227) .

Tested and Certified

Nord-Lock washers are produced to the highest specifications and quality standards and they have been approved by independent institutes as well as certification authorities.

A pair of Nord-Lock X-series washers has cams on one side and serrations on the opposite side to secure the bolted joint with tension instead of friction. The conical shape keeps a continuous reaction force against the parts, compensating for all possible loss of preload in the joint.
