Shape Z: For socket and Allen head screws. The extremely reliable positive locking effect against unscrewing has been verified through the application of a dynamic load (vibration) across the screw axis in many practical tests. Comparison of detent-edge washers to lock washers ● Reusable. ● Protects the counter surface from dam- age (Washer does not turn during instal- lation). ● Minimal tightening torque distribution. ● Universal in use, e.g. also suitable for oblong hole fastening and sheet-metal screw joints. ● Hardened spring steel 420--5100 HV 110, GEOMET ® 321-coated. ● Stainless steel A4. ● Material number 1.4401.
