Professional Applications & Engineering Value

These T6 Torx Drive TRS tapping screws are specifically engineered to address common challenges in plastic assembly applications where traditional fastening methods often fail. The thread forming design with tri-lobe shank cross-section eliminates the risk of plastic cracking by gradually displacing material rather than cutting it, creating strong, permanent threads that resist vibration loosening. The zinc-plated steel construction provides essential corrosion protection while maintaining the strength required for demanding industrial environments. With 28 threads per inch and precise 82° countersink angle, these screws deliver consistent performance in electronic enclosures, automotive plastic components, and consumer products where reliable fastening and aesthetic finish are equally critical. The T6 Torx drive system ensures maximum torque transfer without stripping, significantly reducing assembly errors and improving production line efficiency.

Specification Summary & Compliance

These No. 2 size tapping screws feature a 0.086" thread diameter with 28 TPI fully threaded along the 5/16" length. The standard flat head measures 0.162" in diameter with 0.051" height, designed for 82° countersink applications. Manufactured to precise thread forming standards for plastic materials, these screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and material safety for industrial use worldwide.
