About This Product

■Summary

Nord-Lock washers, which feature a wedge locking mechanism, use axial force rather than friction to physically prevent bolt connections from loosening. Nord-Lock washers greatly reduce the risk of loss due to unexpected production stoppages, accidents, warranty claims, etc., contributing to improved production efficiency and reduced maintenance costs.

■Product structure

When the bolt is tightened, the serrations grip and secure the mating material. When a loosening force is applied, the cam angle α is larger than the screw lead angle β, so the washer becomes thicker and pulls up the bolt head, conversely increasing the axial force. Physically prevents rotational loosening by using the axial force itself.

■Advantages of using Nord-Lock washers

・Prevents bolts from loosening even in environments exposed to severe vibrations and fluctuating loads ・Material that can withstand corrosive, acidic, and high-temperature environments ・Lock function not affected by lubricating oil ・Accurate axial force due to clear and uniform friction - Wide range of metric and imperial sizes ・High corrosion resistance ・Reusable ・Customized size ・Improve operational reliability and reduce maintenance costs ・Reducing the risk of downtime and accidents

■Applications

Nord-Lock wedge locking washers use axial force instead of friction to secure bolt connections that are exposed to severe vibrations and fluctuating loads. Throughout their lifecycle, Nord-Lock washers improve operational reliability and reduce maintenance costs, significantly reducing the risk of production stoppages, accidents, and warranty claims. Nord-Lock washers are used everywhere from the deep sea to outer space and bridges, where safety is a must.
