S-99397A682 Length 12 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with Torx Plus IP15 drive for reduced cam-out and enhanced assembly efficiency.
• Reliable thread formation in plastics using the TRS thread-forming design, minimizing stress and preventing material cracking.
• Excellent corrosion resistance provided by zinc-plated steel, ensuring long-term durability in various environments.
• Secure fastening with Tri-Lobe shank that resists rotation after installation, maintaining joint integrity.
• Optimized for plastic assemblies with a blunt tip and fully threaded M3.63 size for consistent performance without pre-drilling in many cases.
• Broad compatibility with standard 1/8" drill bits, simplifying installation and reducing tooling requirements.
• Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe and sustainable use in global markets.

Professional Applications & Engineering Value

This M3.63 zinc-plated steel TRS tapping screw is engineered to address common challenges in plastic assembly applications, such as material stress and thread stripping. The thread-forming (TRS) design with a Tri-Lobe shank cross-section displaces plastic material to create strong, durable threads without tapping, reducing installation time and tool wear. The Torx Plus IP15 drive offers high torque transfer, minimizing screw head damage and improving operator efficiency. Ideal for electronics enclosures, automotive plastic components, and consumer goods, this screw ensures reliable performance where vibration resistance and corrosion protection are critical. Its fully threaded 12mm length and 1.34mm thread pitch provide consistent holding power in various plastic thicknesses.

Specification Summary & Compliance

This metric tapping screw features a M3.63 size with fully threaded design and 12mm length, adhering to standard thread-forming tolerances for plastic applications. The pan head style with 7mm diameter and Torx Plus IP15 (T15) drive ensures precise installation. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial use without hazardous substances.
