Nord-Lock
Lockwasher nordlock nl
Art. no.: 214659
Lock washer Nord-Lock in accordance with DIN 25201. Surface treated with Delta Protekt (complies with RoHs and ELV) and manages up to 600 hours in salt spray test in accordance with ISO 9227. Nord-Locks steel washers are made of EN 1.7182 or equivalent steel. All steel washers are tempered/through hardened. Also available in acid-resistant material equivalent to A4-quality.

Nord-Lock consists of pairs of pre-assembled washers with combs on an incline on one side where the comb angle is greater than the angle of the thread pitch and radial teeth on the opposite side. The washers are always mounted in pairs with the comb sides towards each other.
When the screw/nut is tightened, the Nord-Lock washer grips the opposite surfaces, allowing movement only movement along inclined combs. Each attempt to unscrew a screw/nut will be effectively blocked by the kill locking that will take place.

The NOrd-Lock safety washers have an outer diameter adapted for recessed holes as standard. In addition, there are washers with enlarged outer diameters (SP) for use with large/oblong holes, painted surfaces or soft materials such as aluminium. Use Nord Lock SP washers in combination with the flange screw/nut for maximum load distribution.

Nord-Lock screw fusing system can also be used for high strength screws/nuts. Straight through holes require two pairs of washers, both under the head of the screw and under the nuts. Nord-Lock also effectively secures the nut to the stud bolt and eliminates the need for locking fluid.
