Delta PT®
Thread Forming Fasteners for Plastic and Composite Materials
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
