  • Features

    • Head shaped for easy assembly e.g. internal six-lobe recess head for an efficient transmission of torque
    • rs-metric thread
    • Especially designed for direct mounting into light metals and other metals
    • High load transmission due to large minor diameter and two-step thread flank design
    • Metric thread pitch secure hold in the component due to positive fit in self-formed thread
    • Pentagon flats for smooth thread forming and centric positioning of the screw
  • Economic advantages

    • Designed for direct mounting into light metals and metals with minor tensile strength.
    • No previous thread cutting required.
    • Direct mounting without any metal thread inserts.
    • Reduced overall weight of the component or subassembly.
    • Lower overall cost of assembly using rs-metric screws.
  • Quality features

    • Thread forming without chips, no loss of material.
    • Optimized load transmission due to large overlap between thread flanks and component.
    • Enhanced load bearing of component material due to the flat thread angle.
    • Secure hold of the betzer rs-metric screw due to positive fit in the component material.
  • Installation advantages

    • Low manual contact pressure required.
    • Minimized penetration torque due to low material displacement.
    • Large overlap of thread flanks for high overturning torques.
    • Subsequent screw fastening up to 10 times possible.
    • The mounted betzer rs-metric screw resists high stripping forces.
