DIN127b Metal Spring Washer are commonly used metric lock washers, DIN127b Metal Spring Washer a split metal ring that is bent into a helical shape. DIN127b Metal Spring Washer are a left hand helix and allow the nut to be tightened in a right hand direction only. When compressed by tightening the nut, the washer bites into the substrate and exerts a spring force between the bolt and the substrate creating frictional resistance to rotation.
