Nord-Lock Introduces X-Series Washers

Nord-Lock adds a new dimension of safety to bolt security with the launch of the Nord-Lock X-series washer.

X-series combines Nord-Lock’s wedge-locking protection against spontaneous bolt loosening (due to vibration and dynamic loads) with an exclusive spring effect that protects against slackening due to settlement and relaxation. This combination makes X-series a true multifunctional solution — offering security for critical joints.

How it works:
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.
