S-99397A486 Length 12 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in various environments.
• Enhanced torque transmission and reduced cam-out thanks to the Torx Plus IP15 drive, allowing for higher assembly speeds and fewer tool slips.
• Excellent holding power in plastic materials due to the thread forming (TRS) design and tri-lobe shank, which creates strong, secure threads without pre-tapping.
• Streamlined installation process with a fully threaded, blunt tip and standard 1.34mm pitch, enabling quick and consistent fastening in plastic assemblies.
• Durable and consistent performance from the rounded pan head profile, which provides a low-profile, finished appearance and distributes clamping force evenly.
• Compliance with strict environmental standards, including RoHS 3 and REACH, ensuring safe use in regulated industries and global markets.
• Optimized for use with standard 1/8" drill bits, simplifying hole preparation and reducing setup time in plastic fabrication.

Professional Applications & Engineering Value

These M3.63 thread forming screws are specifically engineered to address common challenges in plastic assembly, such as material cracking and stripped threads. The 18-8 stainless steel offers excellent strength and corrosion resistance, while the tri-lobe shank and thread forming (TRS) design displace plastic material to form precise, durable threads without creating chips. This reduces the risk of failure in vibration-prone applications. The Torx Plus IP15 drive ensures efficient torque transfer, minimizing operator fatigue and improving assembly line productivity. Ideal for electronics enclosures, automotive components, and consumer goods, these screws provide reliable fastening in plastic where consistent clamp load and resistance to loosening are critical.

Specification Summary & Compliance

This M3.63 x 12mm screw features a fully threaded design with an approximate thread pitch of 1.34mm and a blunt tip for easy insertion. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards. The metric dimensions and thread forming method provide precise fit and reliable performance in plastic materials, with a recommended drill bit size of 1/8" (0.125") for optimal hole preparation.
