  • Features

    • Collar to support the screw driver and increase the load bearing area.
    • Robust screw with large shank diameter to transmit high tightening torques.
    • Large overlap between thread flanks and material provides secure hold in mounted condition
    • Two-step thread flank design prevents spontaneous loosening

  • Economic advantages

    • No previous thread cutting required.
    • Direct mounting without any metal thread inserts.
    • Thin boss design can be realized.
    • The mounted rs-plast screw resists high stripping forces.
    • Short assembly time (cycles) in automatic mounting.

  • Quality features

    • Thread forming without chips, no loss of material.
    • Optimized load transmission and minimized relaxation due to large overlap between thread flanks and component.
    • The flat thread angle reduces stress in the component.
    • Secure hold due to positive fit in the material.

  • Installation advantages

    • Optimized thread pitch for quick mounting.
    • Minimized penetrationtorque due to lowmaterial displacement.
    • Large overlap of the thread flanks for high overturningtorques.
    • Subsequent screw fastening up to 10 times possible.
