Locking ribs for sensitive surfaces 
Locking ribs under the screw head for sensitive surfaces to prevent loosening.

  • Function

    The ribs cause the supporting surface to deform and then harden, thus increasing the loosening torque of the screw.

  • Features

    • More efficient loosening pro­tection than tooth lock washers or the like.
    • Reduced number of assembly components.
    • Improved feeding at the assembly compared to screws combined with washers.
    • No formation of chips in mounting process.
    • Reduced notching in the component.
    • Reduced costs for the assembly in total.
