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
