FLOWpoint Delta PT


Carbon fiber reinforced plastic (CFRP) continues to set current and future lightweighting trends in the Automotive Industry.

The FLOWpoint DELTA PT® screw is an innovative fastener developed to meet the challenging demands of joining these highly engineered CFRP materials. It combines two proven EJOT technologies into one screw.

The FLOWpoint DELTA PT® is a self-piercing and self-tapping screw that penetrates both the clamped and mating material without a pilot hole. The optimized DELTA PT® thread geometry forms a strong female thread in the carbon fiber-reinforced plastic.


Features of the FLOWpoint DELTA PT®

  • No pilot hole required; tolerance compensation is possible
  • High-quality threaded joint without part preparation
  • Applicable for many varieties of CFRP
  • Easy disassembly and reassembly
  • Available in Stainless Steel, Steel, Aluminum
  • Hybrid joining possible (e. g. Aluminum to CFRP)



  1. Rotation of screw and application of axial end load
  2. Warming up and penetration of the material
  3. Screw hole calibration and formation of extrusion
  4. Thread forming
  5. Full thread engagement
  6. Tightening
