Nord Lock Washer

Nord-Lock Washers are wedge-locking washers designed to secure bolted joints against loosening from vibration and dynamic loads. They work in pairs with cam faces and serrations that create tension, making loosening impossible without deliberate unfastening. Manufactured to DIN 25201 standards, they are available in steel, stainless steel, and specialized alloys. These washers maintain preload and reliability even in extreme vibration or thermal cycling conditions. They are widely used in wind energy, railways, mining, construction, heavy equipment, and automotive industries.
