Professional Applications & Engineering Value

These M4.55 zinc-plated steel TRS tapping screws are engineered specifically for plastic assembly applications where material integrity and joint reliability are critical. The tri-lobe shank design and thread forming technology displace plastic material without creating chips, eliminating cleanup while forming permanent, high-retention threads. The Torx Plus IP20 drive system delivers maximum torque transfer, preventing cam-out and reducing assembly tool wear in high-volume production environments. With their fully threaded 14mm length and 1.59mm pitch, these fasteners distribute clamping force evenly, preventing stress concentration in brittle plastics. The zinc-plated steel construction provides essential corrosion protection for electronics enclosures, automotive components, and industrial equipment where environmental exposure is a concern.

Specification Summary & Compliance

These metric TRS tapping screws feature M4.55 diameter with 1.59mm approximate pitch and 14mm length, designed with fully threaded tri-lobe shank configuration for plastic applications. The fasteners incorporate Torx Plus IP20 drive with pan head style (8mm diameter, 3.1mm height) and blunt tip for controlled penetration. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial markets and electronic applications requiring hazardous substance restrictions.
