Overview

1. Can be used in small bosses
2. Increases product reliability
3. Lowers required drive torque when fastening stiffer thermoplastics

Features

• Trilobular™ configuration allows displaced material to cold flow back into relief areas
• 45° thread profile allows threads to penetrate deeply into plastic material
• Single lead design and narrow helix angle lowers drive torque and failure torque in thermoplastics with a flexural modulus over 850,000 p.s.i.

Benefits

• Minimizes radial stress
• Reduces possibility of boss failure
• Eliminates need for inserts and lock washers
• Allows design of thinner bosses
• Suits a wide choice of applications
• Generates strong mating threads
• Resists vibration loosening
• Increases resistance to strip-out
• Achieves wide differentials between drive and fail torque
• Creates less stress on the boss
