Nord-Lock washer

Nord-Lock washer

Diameter 6 - 12 mm

DIN: 25201

Surface treatment: Delta Protect

Nord-Lock washer pair based on DIN 25201. The use of Nord-Lock washer pair is recommended in case of fixing exposed to especially strong loosening effects (e.g. vibration, dynamic loads). The cogging is inclined on the internal side of the Nord-Lock washer pair, the rising angle of which is bigger than the angle of the thread pitch. If the binding material exposed to vibration or dynamic load came to a loosening direction, the washer pair can only move on the internal, inclined cogging, the tension in the screw increases and a self-closing binding is created. The dowel action of the internal cogging hinders all loosening attempts. The Nord-Lock washer pairs are coated with zinc lamella.
