M 3 High Collar Lock Washer, Steel Zinc. DIN 7980 / ISO 7089

  • DIN 7980, ISO 7089 High Collar Lock Washers have smaller outside diameters than standard split lock washers to fit neatly under socket head cap screws. As a screw is tightened, they flatten to add tension to the joint and prevent loosening from small amounts of vibration.

Similar to CSN 021740, UNI 4464A
