S-99397A484 Length 10 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for humid or demanding environments
• Enhanced torque transfer and reduced cam-out with Torx Plus IP15 drive, ensuring secure fastening and tool longevity
• Reliable thread forming in plastics using the TRS Tri-Lobe shank design, creating strong, vibration-resistant threads without pre-tapping
• Optimized for plastic assembly with a 1.34 mm thread pitch and blunt tip to prevent material cracking or splitting
• Secure and low-profile fastening thanks to the 7 mm pan head design, providing a flush finish and even clamping force
• Full 10 mm threading for maximum grip length and holding power in plastic substrates
• Environmental compliance assurance meeting RoHS 3 and REACH standards, supporting sustainable manufacturing practices

Professional Applications & Engineering Value

This M3.63 TRS thread forming screw is specifically engineered to address common challenges in plastic assembly, such as stress cracking, strip-out, and loosening under vibration. The Tri-Lobe shank cross-section displaces plastic material during installation, forming permanent, high-strength internal threads that resist back-out. Made from 18-8 Stainless Steel, it provides excellent corrosion resistance for outdoor enclosures, electrical housings, and automotive plastic components. The Torx Plus IP15 (T15) drive allows for higher torque application compared to Phillips or slotted drives, reducing installation time and tool wear. Its fully threaded design and 1.34 mm pitch ensure consistent engagement in various plastic densities, from ABS to polycarbonate, making it a reliable choice for high-volume manufacturing and precision engineering applications.

Specification Summary & Compliance

This metric tapping screw features a M3.63 screw size with a 10 mm length and 1.34 mm approximate thread pitch. It incorporates a right-hand thread, fully threaded shank with Tri-Lobe cross-section, and blunt tip for thread forming (TRS type) applications. The drive system is Torx Plus IP15 (T15) with a 7 mm pan head and 2.6 mm head height. Manufactured from 18-8 Stainless Steel, it is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in electronic, automotive, and consumer product assemblies.
