• Complete thread coverage and maximum grip length with fully threaded design along the entire 1" length
• Streamlined installation process with compatible No. 29 drill bit size (0.136" diameter) for precise hole preparation
• Compliance with global environmental standards including RoHS 3 and REACH for international industrial applications

Professional Applications & Engineering Value

These 316 stainless steel TRS tapping screws deliver exceptional performance in plastic fastening applications where corrosion resistance and material integrity are critical. The thread forming technology eliminates the risk of plastic cracking or material stress concentration by creating threads through displacement rather than cutting. The tri-lobe shank cross-section reduces driving torque by up to 30% compared to standard fasteners, preventing damage to delicate plastic components while maintaining superior pull-out resistance. Engineered specifically for plastic assembly applications in automotive, electronics, and outdoor equipment, these screws provide reliable, vibration-resistant connections that withstand environmental exposure and thermal cycling without compromising the structural integrity of plastic substrates.

Specification Summary & Compliance

These No. 8 x 1" TRS tapping screws feature precise dimensional specifications including 0.164" thread diameter, 16 TPI thread pitch, and standard Class 2A thread tolerances. The pan head design with 0.322" diameter and 0.115" height provides optimal bearing surface for plastic applications. Manufactured to thread forming standards with tri-lobe shank geometry and blunt tip for controlled penetration. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial applications worldwide.
