Duro PT® Thread-Cutting Screws
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 feature 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.
