• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

Engineered specifically for plastic fastening applications, these No. 6 zinc-plated steel TRS tapping screws solve critical assembly challenges in industrial settings. The unique Tri-Lobe shank design and thread-forming technology displace plastic material during installation, creating permanent threads that resist loosening under vibration and thermal cycling. This eliminates the need for additional inserts or adhesives, reducing assembly time and costs. The external hex drive provides superior torque transmission compared to Phillips or slotted drives, preventing cam-out during high-volume production. With full threading and blunt tip, these screws distribute clamping force evenly while preventing plastic cracking at the entry point. Ideal for electrical enclosures, automotive trim, consumer electronics, and industrial equipment where reliable plastic-to-plastic or plastic-to-metal connections are essential.
