Professional Applications & Engineering Value

These No. 8 thread forming screws are specifically engineered to address common challenges in plastic fastening applications, where traditional fasteners often cause material cracking or stripping. The Tri-Lobe shank design and thread forming technology create precise, durable threads in plastic substrates without generating chips, eliminating cleanup and ensuring consistent clamp load. The zinc-plated steel construction provides essential corrosion protection while maintaining the strength required for long-term structural integrity. With T20 Torx drive delivering superior torque transmission, these TRS screws prevent driver slippage and reduce assembly time in high-volume manufacturing environments, making them ideal for automotive components, electronic enclosures, and consumer products where reliable plastic-to-plastic or plastic-to-metal connections are critical.

Specification Summary & Compliance

These thread forming screws feature precise dimensional specifications including No. 8 screw size (0.164" thread diameter), 1-1/2" length, and 16 threads per inch with full threading. The manufacturing complies with standard thread forming screw specifications for plastic applications, utilizing right-hand thread direction and pan head style with standard rounded profile. Quality assurance includes full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring these fasteners meet international standards for industrial use while maintaining consistent performance across production batches.
