PT® / Delta PT® (Thread-Forming, Torx Plus, Steel/SST)

PT® Thread-forming Screws for Thermoplastics

PT® Thread-FormingWith a high thread profile and recessed thread root, the PT screw provides increased thread engagement with minimal stress on the boss. It provides optimal performance in a wide range of thermoplastics.

Features

  • Narrow 30° thread profile
  • Optimum thread pitch
  • Round body
  • Recessed thread root

    Benefits
  • Provides maximum resistance to back-out and pull-out
  • Minimizes boss failure


    DELTA PT®

    Thread forming screws engineered to create optimal material flow during installation, resulting in better clamp loads and increased joint life in a wide range of plastic materials. DELTA PT fasteners are engineered to provide maximum performance in a wide range of thermoplastics. The improved design results in a stronger fastener that creates optimal material flow during installation, providing higher performance, better clamp loads and increased joint life.

    Features and Benefits
  • Flank geometry engineered to provide better material flow during installation combined with high flank engagement
  • Larger fastener cross-section increases shear area and fastener strength
  • Optimized pitch allows high clamp load with smaller contact pressure

    Benefits
  • Minimizes radial stress
  • Offers increased fatigue life
  • Optimizes material flow
  • Provides increased torsional and tensile strength
  • Can achieve higher clamp loads and seating torques
  • May permit use of shorter fasteners and/or smaller diameters, if necessary

    Design Guidelines
  • Sizes: DELTA PT 14-70 (1.4mm-7.0mm)
  • Head Styles: Can be used with any head design
  • Specials: Shoulder screws, sems, double end studs, collar studs
  • Drive Systems: TORX PLUS® Drive is recommended to facilitate the proper amount of torque transfer required for forming threads
  • Other styles also available
