S-99397A189 Length 8 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability
• Enhanced torque transmission and reduced cam-out thanks to the Torx Plus IP6/T6 drive, ensuring secure fastening and minimal tool wear
• Excellent holding power in plastic materials due to the Tri-Lobe shank design, which forms strong, reliable threads without pre-tapping
• Streamlined assembly process with fully threaded, blunt tip design for easy starting and consistent performance in plastic applications
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries
• Precision metric sizing (M2.26 x 8mm) for accurate fit and consistent performance in specialized plastic assemblies

Professional Applications & Engineering Value

This M2.26 Torx Plus TRS plastic tapping screw is engineered to address common challenges in plastic assembly, such as material cracking and stripped threads. The thread forming (TRS) design with a Tri-Lobe shank cross-section displaces plastic material to create strong, permanent threads without generating chips, reducing the risk of failure. Made from 18-8 stainless steel, it offers excellent corrosion resistance, making it suitable for electronics, automotive components, and outdoor equipment. The Torx Plus drive (IP6/T6) ensures high torque transfer, minimizing slippage and improving assembly efficiency in high-volume production lines.

Specification Summary & Compliance

This screw features a metric M2.26 size with an approximate thread pitch of 0.91 mm and fully threaded right-hand threading. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict environmental and safety standards for industrial use. Designed for use in plastics with a recommended drill bit size of 5/64" (0.0781"), it provides reliable performance in precision applications.
