Duro PT thread-cutting screws are engineered to meet the demanding requirements of thermoset plastics, easing assembly and ensuring a strong, reliable joint to maximize assembly performance.

Duro PT screws features an asymmetrical 30° thread profile, inclined towards the load surface to increase friction between the application and the fastener.  This feature reduces radial stress, reduces back-out caused by relaxation, increases strip resistance, and eliminates need for supplementary locking devices.

Fast Facts: 

  • Cuts threads in stiffer plastics
  • Minimizes installation torque

  • Recessed thread root provides space for displaced material
