S-99397A224 Length 6 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission and reduced cam-out with the Torx Plus IP6 drive, ensuring reliable fastening and extended tool life in repetitive assembly operations.
• Excellent corrosion resistance provided by the zinc-plated steel finish, protecting the screw in various industrial environments and enhancing product longevity.
• High-strength, secure threads in plastic materials due to the thread-forming (TRS) design and tri-lobe shank, which create strong, vibration-resistant connections without the need for pre-tapped holes.
• Optimized for efficient plastic assembly with a blunt tip and fully threaded 6mm length, allowing for easy starting and consistent thread engagement to prevent material cracking.
• Wide compatibility and precise fit with a standard pan head and M1.91 metric size, ensuring easy integration into existing designs and tooling setups.
• Streamlined installation process using a standard No. 51 drill bit (0.067"), reducing setup time and improving overall assembly line efficiency.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe use in regulated markets and sustainable manufacturing practices.

Professional Applications & Engineering Value

This M1.91 x 6mm TRS tapping screw is engineered to address common challenges in plastic assembly, such as strip-out and material stress. The thread-forming action of the tri-lobe shank displaces plastic material to create robust, permanent threads, eliminating the need for inserts and reducing component count. Made from zinc-plated steel, it offers durability against corrosion in electronics, automotive trim, and consumer goods applications. The Torx Plus IP6 drive provides superior torque transfer, minimizing slippage and operator fatigue during high-volume production. With a 0.79mm thread pitch and blunt tip, it ensures precise, crack-free installation in thermoplastics and other polymers, enhancing assembly reliability and reducing waste.

Specification Summary & Compliance

This metric screw features a M1.91 diameter and 6mm length with a 0.79mm thread pitch, designed for thread-forming applications in plastics. It includes a standard pan head with Torx Plus T6/IP6 drive and is fully threaded with a blunt tip. Manufactured to precise dimensional standards for reliable performance, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety requirements in industrial use.
