Professional Applications & Engineering Value

This M3 TRS tapping screw delivers exceptional engineering value in plastic assembly applications where material integrity and joint reliability are critical. The thread forming technology creates permanent, high-strength threads in thermoplastic and thermoset materials without generating chips that could contaminate sensitive components. The 18-8 stainless steel construction provides excellent resistance to corrosion and chemical exposure, while the Torx T8 drive system ensures maximum torque transfer without stripping during high-volume production. With its 1.34mm pitch and fully threaded design, this fastener distributes clamping force evenly, preventing stress concentration and material cracking in delicate plastic housings, electronic enclosures, and automotive interior components.

Specification Summary & Compliance

This metric M3 x 8mm TRS tapping screw features standard thread forming technology with fully threaded blunt tip design and right-hand thread direction. The fastener maintains precision dimensional standards with 5.5mm head diameter and 1.8mm head height for consistent performance. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial suitability. The specified No. 41 drill bit (0.096") and 90° countersink angle provide proper installation parameters for optimal thread engagement in plastic materials.
