S-99397A417 Length 12 mm Tapping Screws

Key Features & Benefits at a Glance

• Enhanced torque transmission with Torx Plus IP8 drive prevents cam-out and reduces tool wear
• Superior thread-forming performance in plastic materials with TRS tri-lobe shank design
• Corrosion-resistant zinc plating extends service life in demanding industrial environments
• Optimized plastic assembly with blunt tip and fully threaded design prevents material cracking
• Secure fastening integrity maintained through precise M2.63 sizing and 1.06mm pitch threading
• Streamlined installation process using standard No. 43 drill bit for consistent hole preparation
• Regulatory compliance assurance with RoHS 3 and REACH standards for global market acceptance

Professional Applications & Engineering Value

These M2.63 zinc-plated steel TRS tapping screws deliver exceptional value in plastic assembly applications where material integrity and installation efficiency are critical. The thread-forming TRS design with tri-lobe shank creates strong, permanent threads in plastic substrates without generating chips, eliminating contamination risks in sensitive assemblies. The Torx Plus IP8 drive system ensures maximum torque transfer while minimizing stripping incidents common in high-volume production environments. Combined with the fully threaded blunt tip configuration, these screws distribute stress evenly throughout the plastic material, preventing stress concentration and material failure. This makes them ideal for automotive trim components, electronic enclosures, and consumer product assemblies where reliable plastic-to-plastic or plastic-to-metal fastening is required.

Specification Summary & Compliance

These metric M2.63 x 12mm TRS tapping screws feature standard ISO thread tolerances with 1.06mm pitch and fully threaded tri-lobe shank design. Manufactured from zinc-plated steel with pan head style and Torx Plus IP8 drive, they comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The screws are engineered for use with No. 43 drill bit (0.089") and are designed specifically for thread-forming applications in plastic materials.
