S-99397A758 Length 6 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 IP20/T20 drive, providing secure fastening and minimizing tool wear.
• Excellent thread retention in plastic through the thread-forming TRS design and Tri-Lobe shank, which displaces material to create strong, vibration-resistant threads without pre-tapping.
• Consistent, flush installation with the pan head style and standard rounded profile, offering a neat finish and even load distribution.
• Full-length threading for maximum grip across the entire 6mm length, ensuring uniform holding power in plastic assemblies.
• Compliance with environmental regulations, including RoHS 3 and REACH, making it suitable for global markets and sensitive applications.
• Optimized for use with standard drill bits (No. 23 / 0.154"), simplifying installation and reducing preparation time.

Professional Applications & Engineering Value

This M4.55 x 6mm Torx Plus TRS thread forming screw is engineered to address common challenges in plastic assembly, such as strip-out, loosening under vibration, and material cracking. The 18-8 stainless steel offers excellent durability and corrosion resistance, while the thread forming (TRS) design with Tri-Lobe shank cold-forms mating threads in plastic, eliminating the need for pre-tapped holes and reducing assembly steps. This results in higher pull-out strength and resistance to back-out, making it ideal for electronics enclosures, automotive trim, and consumer products where reliable, vibration-resistant fastening is critical. The Torx Plus drive ensures efficient torque application, minimizing the risk of damage to the screw or workpiece during installation.

Specification Summary & Compliance

This screw features a metric M4.55 size with an approximate thread pitch of 1.59mm, fully threaded design, and right-hand thread direction. It complies with industry standards for thread-forming screws and is manufactured to precise dimensional tolerances. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets strict environmental and safety regulations for hazardous substances.
