Tri-Lobular Thread Forming Screws for Plastic Applications

Plastic applications pose an interesting advantage when designing for the proper fastener.  Because of many plastics’ cold-flow characteristics, after a hole is tapped with a Tri-Lobular Thread Forming Screw the mating material will recover and settle back into the area between the seated fastener’s threads. This provides a form fit that is exceptional in its resistance to vibrational loosening.  Because no material is specifically removed during the tapping process, structural integrity of the original substrate is not compromised.  And the deep, widely spaced threads of the Tri-Lobular Thread Forming Screw provide a high degree of thread engagement which further enhances this fastener’s holding ability.
