Nord-Lock X-series washer
Nord-Lock said it has added a new dimension of safety to bolt security with the launch of the Nord-Lock X-series washer.
X-series combines Nord-Lock’s unmatched wedge-locking protection against spontaneous bolt loosening due to vibration and dynamic loads with an exclusive spring effect to protect against slackening due to settlement and relaxation. This unique combination makes X-series the first, true multifunctional solution — offering the highest security for critical joints, without compromise.
As with Nord-Lock’s original washers, each washer pair has cams on one side and radial teeth on the opposite side to secure the bolted joint with tension instead of friction. The Nord-Lock X-series washers’ conical shape also creates an elastic reserve in the bolted joint to compensate for the loss of preload and prevent slackening.
