REMFORM®

REMFORM® fasteners help lower the cost of assembly in engineered plastic materials. By eliminating weight while providing the requisite fastening performance, REMFORM® fasteners create value for designers, manufacturers and end users. REMFORM® fasteners combine a thread form that promotes efficient material flow during thread-forming while also creating exceptional resistance to pullout forces. REMFORM® fasteners’ ability to create high quality internal threads while minimizing the risk of boss bursting in the assembly process makes them an excellent thread-forming fastener.

FEATURES

► The original REMFORM® screw first featured the unique asymmetrical thread profile that minimizes radial hoop stress to reduce boss bursting
► The narrow tip angle also reduces stress in the plastic nut member

BENEFITS

► Reduced hoop stress
► Optimal material flow
► Easy assembly

The EVO PT® is the evolutionary development of self-tapping fasteners for thermoplastics. The innovative thread forming feature creates a consistent torque curve that is independent of screw-in depth. This allows for uniform tightening torque for screws of different lengths of engagement.

FEATURES

► Unique lead in thread forming feature that creates similar tightening torque with different length screws
► Axial alignment
► Larger fastener cross-section optimizes shear area and fastener strength

BENEFITS

► Allows the use of 1 fastener length in multiple locations while maintaining the same seating torque
► Good fatigue resistance
► Optimizes material flow
► Provides increased torsional and tensile strength

DELTA®-PT fasteners offer an improvement over the proven performance of PT® fasteners. 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, provides 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
► 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
► Can achieve higher clamp loads and seating
torques
► Provides increased torsional and tensile strength
► May permit use of shorter fasteners and/or
smaller diameters, if necessary

The PLASTITE® 48 fastener combines a unique tri-lobular body with a 48° thread profile to maximize performance and reliability. Two thread-forming styles are available to meet the specific requirements of a wide range of thermoplastics.

FEATURES

► Tri-roundular configuration allows displaced material to cold flow back into relief areas
► 48° thread profile allows threads to penetrate deeply into
plastic material
► Generates strong mating threads

BENEFITS

► Creates less stress on the boss and reduces chances for boss failure
► Eliminates need for inserts and lock washers
► Reduces probability of strip-out and pull-out
