1:Trilobular thread-forming screw

The trilobular thread-forming screw(also call it triangular tapping screw) allows the plastic material to recover and fill in between the lobes, which leads maximum resistance to vibrational loosening and provides a heavier shear area and deeper thread engagement in the plastic, further enhancing holding capabilities.

2:Main characteristic

  • Easy entry
  • Lower installation torque
  • High resistance to relaxation and vibration loosening
  • Suitable for a wide range of thermoplastic material and all holes of punch extruded metals
