S-99397A482 Length 8 mm Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with 18-8 Stainless Steel construction, ideal for demanding industrial environments.
• Superior torque transmission and reduced cam-out thanks to the Torx Plus IP15 drive system, ensuring reliable installation.
• Secure, vibration-resistant fastening in plastics achieved by the Tri-Lobe shank design, which forms strong, lasting threads.
• Streamlined assembly process with a fully threaded, blunt-tip design for easy starting and consistent performance.
• Long-term reliability and material integrity from the thread-forming (TRS) tapping method, which eliminates chips and debris.
• Broad industrial compliance with RoHS 3 and REACH regulations, ensuring safety and environmental standards are met.
• Precise M3.63 x 8mm metric sizing with a 1.34mm thread pitch for accurate fit in designated plastic components.

Professional Applications & Engineering Value

This M3.63 Torx Plus TRS tapping screw is engineered to solve common fastening challenges in plastic applications. Its thread-forming design, combined with a Tri-Lobe shank, displaces material to create robust internal threads without generating chips, preventing contamination and ensuring a clean, secure fit. The 18-8 Stainless Steel material offers excellent corrosion resistance, which is vital for electronics enclosures, automotive interiors, and outdoor equipment where moisture exposure is a concern. The Torx Plus IP15 drive allows for higher torque application compared to standard drives, reducing the risk of tool slippage and head stripping during installation. This results in fewer assembly errors, increased production line efficiency, and a more reliable end product that withstands vibration and thermal cycling.
