The Plastite® 45 screw is designed to facilitate thread-forming in less-compressible plastics while providing high resistance to strip-out and pull-out. The single-lead design and narrow helix angle lowers drive torque and failure torque in stiffer plastics.

The 45° thread profile allows threads to penetrate deeply into plastic material and generate strong mating threads which resist vibration loosening. The tri-roundular configuration allows displaced material to cold-flow back into relief areas.

Plastite® 45 has smaller root and major diameters than Plastite® 48, so it can be used in smaller bosses.

Fast Facts:

  • 45° thread profile
  • Penetrates deeply into plastic material
  • Reduces possibility of boss failure
  • Increases product reliability
  • Eliminates need for inserts and lock washers
  • Minimizes radial stress
  • Allows design of thinner bosses
  • Generates strong mating threads
  • Resists vibration loosening
  • Reduces probability of strip-out and pull-out
  • Achieves wide differentials between drive and fail torque
  • Creates less stress on the boss
