Nord-Lock Offers Loosening-Free Washers

Fri, 11/09/2012 - 10:05am

Nord-Lock (Chicago, Ill.) has launched its Nord-Lock X-series washer, which combines the company’s wedge-locking protection against spontaneous bold loosening due to vibration and dynamic loads. An exclusive spring effect protects against slackening due to settlement and relaxation. According to the company, this combination makes the X-series the first true multi-functional bolting solution without compromises. Each X-series washer pair has cams on one side, and radial teeth on the other, to secure the bolted joint with tension instead of friction. A conical shape also creates an elastic reserve in the bolted joint to compensate for the loss of preload and to prevent slackening.
