The PLASTITE 48 screw combines a unique TRILOBULAR™ body with a 48° thread profile to maximize performance and reliability.

The 48° thread profile allows threads to penetrate deeply into plastic material. This generates strong mating threads, helps resist vibration loosening, and reduces probability of strip-out and pull-out.

The proprietary TRILOBULAR body design features a tri-roundular configuration that allows displaced material to cold flow back into relief areas.

Two thread-forming styles are available to meet the specific requirements of a wide range of thermoplastics. The Twin Helix Style works with thermoplastics with a flexural modulus up to 850,000 p.s.i. The single helix style is best for thermoplastics with a flexural modulus between 850,000 p.s.i. and 1,400,000 p.s.i.
