The product page for the registered NETIS item, "Nord-Lock Washer" for preventing bolt loosening, has been updated.
The "Nortlock Washer" is a product that exhibits a powerful anti-loosening effect simply by being placed under bolts and nuts and tightened once.
By inserting a pair of washers that have a cam surface and radial rib surface, the axial force increases when loosening forces are applied, achieving anti-loosening without relying on friction. It is resistant to vibration and shock, providing a long-lasting anti-loosening effect.
