Professional Applications & Engineering Value

These TRS tapping screws are specifically engineered for plastic applications where traditional fasteners fail. The thread forming Tri-Lobe shank design eliminates material chipping and stress cracking common in brittle plastics, while the Black Oxide Steel construction provides essential corrosion protection in demanding environments. The T10 Torx drive delivers exceptional torque transmission, preventing stripping during high-torque installation in automated assembly lines. With a precise 82° countersink angle and flat head profile, these screws sit flush with surfaces, creating clean finishes in consumer electronics, automotive trim, and industrial enclosures. The fully threaded design ensures maximum holding power in thermoplastic and composite materials, making them ideal for vibration-prone applications where fastener security is critical.

Specification Summary & Compliance

This No. 6 x 3/8" TRS tapping screw features a 0.138" thread diameter with approximately 19 threads per inch, right-hand thread direction, and blunt tip configuration. Manufactured to precise dimensional standards with a 1/8" drill bit size recommendation for optimal performance in plastic substrates. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors while maintaining consistent quality and reliability in thread forming applications.
