TFC Ltd. Nord-Lock Steel Washers Nord-Lock Steel Washers

Nord-Lock washers are easy and effective to use while ensuring structural security for applications exposed to vibration and dynamic loads. Dimensions: millimetres Material: Steel EN 1.7182 or equivalent Finish: Zinc Flake Coating (Delta Protekt), through hardened Installing the washers The pre-assembled washers are installed in pairs, cam face to cam face. Nord-Lock recommends lubrication when possible. Tightening Tighten Nord-Lock washers with standard tools according to the torque guidelines below. Tightening guidelines for other bolt grades are available through your Nord-Lock representative. Untightening Untightening Nord-Lock washers is as simple as tightening. Note that since the locking function is not based on increased friction, the untightening torque is generally lower than the tightening torque. Therefore it is not possible to measure offtorque as verification of locking function. Reusing Nord-Lock Nord-Lock washers can normally be reused. As with all fasteners, they should be inspected for wear before reassembly. Make sure that the washers are reinstalled correctly cam face to cam face. Nord-Lock recommends lubrication of fasteners before reuse in order to minimize changes in friction conditions.
