Tri-Lobular Thread Forming Screws for Plastic Applications
Tri-Lobular thread-forming screws are special fasteners designed for use in plastic materials. They feature a unique three-lobed design that displaces plastic material rather than cutting it. As the screw is driven into a plastic surface, the plastic conforms around the screws’ threads, locking the screw in place. This design creates a firm hold that resists vibration while preserving the integrity of the plastic material.
