1. Nord-Lock Wedge lock washers NL12sp zinc flake coated, to DIN25201
Nord-Lock - Screw Locking Without Compromise
The original Nord-Lock wedge locking washers are known worldwide for securing bolted connections that are exposed to strong vibrations and dynamic loads. With their unique wedge locking technology and high-quality materials, Nord-Lock wedge locking washers are the safest and most reliable screw locking elements in the world.
The original Nord-Lock wedge locking washers are a purely mechanical fastening element according to DIN 25 201, securing bolted connections through clamping force rather than friction.
The Operating Principle
Nord-Lock screw locking systems consist of a pair of wedge locking washers with opposing wedge surfaces that interlock. This creates a wedging effect that prevents the screw from loosening. The shape of the wedge surfaces is designed so that the angle "a" is always greater than the thread pitch "ss." When tightening the bolted connection, the radial ribs form a positive fit into the counter surface. The Nord-Lock wedge locking washer pair stays firmly in place, and movement is only possible between the inner wedge surfaces. Even with the slightest rotation in the loosening direction, the wedging effect increases the preload force—thus, the screw secures itself.
When loosening the bolted connection, a so-called click effect occurs due to the sliding of the inner wedge surfaces. Under these conditions—positive fit and click effect—Nord-Lock secures every bolted connection, even under strong vibration and dynamic loads.
The Advantages
Original Nord-Lock wedge locking washers secure bolted connections that are exposed to strong vibrations and dynamic loads. A wide selection of different dimensions and materials is available for use in general steel and stainless steel applications.

4. Nord-Lock Washer R 88132 glued NL 6 hardened and tempered steel zinc flake coated
The NORD-LOCK® wedge locking washer pair is a purely mechanical machine element that secures the screw connection through preload force instead of friction, making it superior to conventional screw locking methods.
When the screw or nut is tightened, the radial ribs of the NORD-LOCK® locking washers form a positive interlock with the counter surface. The washer pair sits firmly in place, and movement is only possible between the wedge surfaces. Even with the slightest rotation in the loosening direction, the wedge effect increases the preload force - thus, the screw secures itself. NORD-LOCK® provides reliable screw locking, even under extreme vibrations or dynamic loads. Due to the high hardness of the washers, they can also be used with high-strength screws up to and including strength class 12.9.
