S-96817A797 Length 4 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in various industrial environments.
• Enhanced torque transmission and reduced cam-out via the Torx Plus IP5 drive, providing secure fastening and minimizing tool wear.
• Efficient thread forming in plastics with TRS design, creating strong, permanent threads without pre-tapping and reducing assembly steps.
• Consistent flush seating thanks to the rounded pan head profile, offering a neat finish and even load distribution on plastic surfaces.
• Full-length threading ensures maximum grip and holding power along the entire 4mm length for robust plastic assemblies.
• Simplified installation with a blunt tip and compatibility with No. 55 drill bits, preventing material splitting and enabling precise alignment.
• Compliance with environmental regulations including RoHS 3 and REACH, making it safe for use in global markets and sensitive applications.

Professional Applications & Engineering Value

This M1.6 x 4mm Torx Plus TRS plastic tapping screw is engineered to address common challenges in plastic assembly, such as thread stripping and material cracking. The 18-8 stainless steel material provides excellent strength and corrosion resistance, ideal for electronics, automotive components, and consumer goods exposed to humid conditions. Its thread forming technology displaces plastic material to create durable internal threads, eliminating the need for inserts and reducing part count. The Torx Plus IP5 drive ensures high torque transfer with minimal slippage, speeding up production lines while the fully threaded blunt tip design prevents damage during insertion, ensuring reliable performance in plastic applications like enclosures and mounting brackets.

Specification Summary & Compliance

This screw features a metric M1.6 size with an approximate thread pitch of 0.64 mm, right-hand threading, and a fully threaded shank for consistent engagement. It adheres to standard dimensional tolerances for precision fit and is designed for use with a No. 55 drill bit (0.052" diameter). The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for environmentally conscious manufacturing processes.
