PLASTITE® TRILOBULAR® thread-rolling screws were developed specifically for use in plastics. They combine a unique TRILOBULAR® cross-sectional form with deep, wide, spaced threads.

PLASTITE® screws are legacy products and have been superseded by REMFORM® II HS™ screws. We keep inch series in stock and produce as custom-made product.

There are different types of PLASTITE® threads, depending on the requirements of the assembly: PLASTITE® 60, PLASTITE® 45 and PLASTITE® 48-2.


PLASTITE® screw benefits

  • TRILOBULAR® thread section reduces radial stress and thread forming torque.
  • Flat crest lead thread enhances screw alignment and material displacement during thread forming.
  • Main feature of PLASTITE 48-2 screws is the twin-lead thread which increases friction and improves stripping resistance.
  • Recommended for plastics with a flexural modulus up to 850,000 psi.
