rs-metric

Thread forming screw for metal and light metal connections

Designed for direct mounting into light metals and metals with minor tensile strength.

  • 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
  • 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.
  • 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.
  • 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.
