• Precision engineering with M4.55 metric sizing and 6mm length for consistent performance in plastic assemblies

Professional Applications & Engineering Value

This zinc-plated steel TRS tapping screw delivers exceptional value in plastic fastening applications where traditional screws fail. The thread forming capability eliminates the need for pre-tapped holes while the tri-lobe shank cross-section displaces material to create permanent, high-strength threads that resist loosening under vibration. The Torx Plus IP20 drive system provides superior torque transfer compared to conventional drives, reducing installation time and preventing fastener damage. Engineered specifically for plastic applications, this M4.55 fastener combines the corrosion resistance of zinc plating with the structural integrity of steel, making it ideal for automotive trim, electronic enclosures, and consumer products where reliability and compliance with environmental standards are critical.

Specification Summary & Compliance

This metric thread forming screw features M4.55 diameter with 1.59mm pitch and 6mm length, manufactured to precise dimensional standards with fully threaded right-hand configuration.
