S-99397A411 Length 3 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with Torx Plus IP8 drive, minimizing cam-out and tool wear during installation
• Exceptional holding power in plastic materials thanks to the tri-lobe shank design that displaces material to form strong, permanent threads
• Enhanced corrosion resistance from the zinc-plated steel construction, ensuring long-term reliability in various environments
• Streamlined plastic assembly with thread-forming (TRS) design, eliminating the need for pre-tapped holes and reducing production steps
• Precise, secure fastening with a consistent 1.06 mm thread pitch and fully threaded M2.63 body for uniform load distribution
• Broad industrial compliance meeting RoHS 3 and REACH regulations, making them suitable for global supply chains
• Optimized for automated driving with a blunt tip and right-hand threading for efficient, high-volume assembly lines

Professional Applications & Engineering Value

These M2.63 TRS tapping screws are precision-engineered for plastic assembly challenges, where traditional fasteners often strip or fail. The zinc-plated steel material provides a durable, corrosion-resistant base, while the Torx Plus IP8 drive ensures maximum torque transfer with minimal slippage—critical for repetitive installation in electronics, automotive trim, and consumer goods. The tri-lobe shank and thread-forming action create tight, vibration-resistant threads in plastic substrates without cracking, reducing the need for inserts and improving structural integrity. This combination of high-performance drive and optimized threading delivers faster cycle times and lower rejection rates in industrial settings.

Specification Summary & Compliance

This metric TRS tapping screw features a 3mm length, M2.63 diameter, and 1.06 mm thread pitch with a tri-lobe shank for thread-forming applications in plastic. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for industrial use. The Torx Plus IP8 (T8) drive provides precise torque control, and the fully threaded, blunt-tip design supports efficient driving in automated or manual assembly processes.
