About Nord-lock

The company offers a wide range of Combi-Bolt and X-Series washers, wedge lock washers, spring lock washers, socket set screws and wheel nuts. The easy-to-install / remove Nord-Lock wheel nuts come pre-lubricated and are designed to secure wheels of on-road and off-road vehicles. Nord-Lock wedge lock washers use tension instead of friction for securing bolted joints that are exposed to dynamic loads or severe vibrations. These washers are made of steel / 254 SMO stainless steel / 316 stainless steel with plain / delta protect finish for resisting corrosion on exposed surfaces. They offer thickness tolerances ranging from +/-0.25 mm to +/-0.03 inches.

Nord-lock Competitive Advantages

Wedge-Locking Technology

Nord-Lock uses wedge-locking technology to ensure that bolted joints cannot be loosened even under severe vibration and dynamic loads. When the nut or bolt is tightened, the teeth grip and seat the mating surfaces. As the cam angle is more than the thread pitch, the cams create a wedge effect, thereby preventing the bolt from loosening while being rotated.' Wedge-lock washers are thus locked in place, allowing movement only across the face of the cam.
