It helps ensure reliable fastening in harder plastics. • Multiple flutes for thread cutting extend through first full thread diameter to reduce radial stress and boss damage • 5° reverse angle of flutes retains chips to minimize contamination • 48° thread profile with extended height, combined with a longer pitch length, increases flank and shear area to increase pull-out resistance and strip-out resistance duro-PT ® Thread-Forming FasTeners Duro-PT ® thread-forming fasteners are engineered to meet the unique requirements of reinforced thermoplastics and light alloys. • Asymmetrical 30° thread profile reduces radial stress and minimizes installation torque • Allows deep thread engagement to increase pull-out strength and increase resistance to vibration loosening • Eliminates need for supplementary locking devices • Recessed thread root provides space for displaced material, minimizing risk of clogging and galling during assembly hi-Wide Thread-Forming FasTeners • Large minor diameter • 40°, 45°, or 48° thread profiles available • Wide thread spacing for greater shear area to increase pull-out resistance • Thread-forming and thread-cutting styles are available • Variety of point styles available for thread-forming screws
The TORX PLUS ® Drive System is the ideal drive system for screws for plastics, since it provides optimum torque transfer, even when forming or cutting threads in reinforced plastics. Its unmatched ability to increase productivity by outperforming competing drive systems can lower assembly costs. sPeciFicaTions Drive Sizes • 1IP – 100IP (recess) to fit screw sizes M0.9 – M24 (#0 – 1") Styles • Internal, external, low-profile external, tamper-resistant, TORX PLUS® Drive/external hex or TORX PLUS Drive/ slotted Drive Tools • TORX PLUS Drive tools fit both inch and metric fasteners. Standard and special tooling is available from over 3,000 outlets around the world.
