Best-in-Class plastic tapping with a variety of sizes and configurations.

Innovative Forming Thread

What is PT®?

PT® is a self-tapping fastening screw used for thermoplastic materials. PT® was designed with manufacturing and application technology based on physical computer models and simulations. 

Why PT® works:

PT® has an innovative thread design that creates a torque curve during the installation phase that is independent of the screw depth.

Efficiency of PT® connections

Direct assembly using the PT screw makes thin-walled and flat designs possible. This leads to material savings and reduced cycle times during injection moulding.

Radial Forces

  • Low radial force – equals low radial stress.
  • Large axial component – for optimum material flow into the recessed thread root.

Displacement Volume

  • Larger thread bearing depth – for increased load-carrying capacity.
  • Lower installation torque – because of smaller leverage with the same displacement volume.
