Powerful, form-fitting locking of screw connections against loosening and unscrewing


  • Type M: for high-strength connections with normal head contact

  • Hardened spring steel, 420-510 high strength 10, GEOMET® 321-coated

  • Spring force for friction-fit connection

  • Specially embossed surface for form-fit connection

  • Reusable

  • Protects the counter surface from damage (washer does not turn during installation)

  • Minimal tightening torque distribution

  • Universal application, e.g. also suitable for slot fastening and sheet-metal screw joints
Notice

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.
