Delta PT® Fasteners

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.

Overview

Delta PT® screws are engineered to provide maximum performance in a wide range of thermoplastics. The improved design results in a stronger joint that creates optimal material flow during installation, providing higher performance, better clamp loads and increased joint life.

Features

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

Benefits

  • Minimizes radial stress
  • Offers increased fatigue life
  • Provides increased torsional and tensile strength

Design Guidelines

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