Professional Applications & Engineering Value

These zinc-plated steel TRS tapping screws deliver exceptional engineering value for plastic assembly applications where traditional fastening methods often fail. The thread forming design creates strong, permanent threads in plastic materials without generating chips or debris that could compromise electronic components or moving parts. The Tri-Lobe shank cross-section provides superior resistance to vibration loosening, making these No. 8 plastic fasteners ideal for automotive trim, electrical enclosures, and consumer electronics where reliable performance is critical. The Torx Plus IP20 drive system ensures maximum torque transfer while minimizing strip-out incidents, reducing assembly time and improving production efficiency in high-volume manufacturing environments.

Specification Summary & Compliance

These thread forming tapping screws feature precise No. 8 size with 0.164" thread diameter and 16 TPI thread pitch in right-hand direction. The pan head design with 0.322" diameter and 0.115" height provides ample bearing surface. Manufactured to TRS (Thread Rolling Screw) standards with fully threaded Tri-Lobe shank configuration and blunt tip for optimal performance in plastic materials. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for industrial applications requiring strict material compliance.
