DIN 127
Flat Washer
Equivalent Standard: ISO 7090
Metric DIN 127 Helical Spring Split Lock Washers are commonly used metric lock washers – It is a split metal ring that is bent into a helical shape. Split Lock Washers 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. DIN 127 are available in two forms, type A and type B. Type DIN 127 A have bent up tang at both ends of the washer. Type B simply have square/straight ends.
