Nord Lock Washers

In 1982, the original Nord-Lock® wedge-locking technology that safely secures bolted joints was developed. Since then, our range of innovative bolting technologies and expertise has grown to be the most comprehensive on the market, incorporating Superbolt™ mechanical tensioners, Boltight™ hydraulic tensioners and Expander® System pivot pins. Nord-Lock Group has tightened and secured billions of bolted connections in millions of applications all over the world. All our solutions are developed and manufactured in-house, ensuring they meet the highest standards in the industry. We are the first bolt-securing partner to offer a full life-cycle warranty across all its technologies. Wedge-Lock Washers Nord-Lock wedge-locking washers utilise tension instead of friction in order to secure bolted joints exposed to severe vibration and dynamic loads. Over the operational life cycle, Nord-Lock washers offer increased operational reliability and lower maintenance costs, while significantly reducing the risks of production stops, accidents and warranty claims. X-series Washers The Nord-Lock X-series washers combine Nord-Lock wedge-locking with an innovative spring effect, offering the highest security against spontaneous bolt loosening and slackening. This product is the optimum choice when you have both vibrations and applications with risk of slackening such as 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. Steel Construction Washers Nord-Lock steel construction (SC) washers are wedge-locking washers specially designed for use on steel construction applications and to fit HV/HR sets bolts and nuts in accordance to the European standard EN 14399-3 /EN 14399-4 /EN 14399-8. In order to ensure an optimal contact surface between the bolt and the washer, each SC-washer pair has chamfers on the inner diameter. Since the chamfer is present on both sides of each pair, it eliminates the risk of incorrect installation of the washer. Nord-Lock steel construction washer promises the highest corrosion resistance in the market, it is tested at least 1,000 hours in the Neutral Salt Spray Test Combi bolt washers Nord-Lock combi bolt washers are specifically designed to be permanently attached to a bolt (SEMS), providing an additional layer of security to applications. The standard range of Nord-Lock combi bolt washers consists of NL5 - NL12 in steel material. Complete combi bolts, including Nord-Lock combi bolt washers, are offered in co-operation with a local bolt manufacturer.
