S-trax® – Your master for direct assemblies

Self-tapping – maximum strength – resilient

In brief

The self-tapping screw for light metal is the evolution of our patented and proven SLS® screw. We developed it for use in light metal materials and other nonferrous metals and it is used for direct assemblies in materials up to a max. hardness of 140 HB. The use of our S-trax® causes maximum strength of the connection and lowers production costs.

S-trax® advantages

  • Process cost savings up to 40%
  • High over-tightening protection
  • High breakaway torque
  • Increased load carrying capacity compared to metric screws
  • Larger pull-out forces
  • Small screw-in torques, high pre-load forces
  • Compatible with metric thread
  • Kostengünstig

The special part about it…

... optimized thread geometry

  • Optimum flank geometry due to asymmetric flanks for improved material displacement
  • Conical thread core for optimal material mounting
  • High flank coverage through circular cross section provides great strength
  • Metrically compatible through a metric thread pitch

... Corrosion protection

Our screws can be made with all commercially available corrosion protection surfaces. For details, please refer to our brochure on corrosion protection which you can download here.
