S-99397A675 Length 6 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission and reduced cam-out with the Torx Plus IP15 drive, ensuring reliable installation and extended tool life in repetitive assembly operations.
• Excellent corrosion resistance and durability provided by the zinc-plated steel construction, making it suitable for various industrial environments.
• High resistance to loosening and pull-out due to the tri-lobe shank design, which creates a secure, vibration-resistant fit in plastic materials.
• Efficient, cold-forming thread creation with the TRS thread-forming design, eliminating the need for pre-tapped holes and reducing assembly time and cost.
• Broad compatibility with standard tools using the T15 drive size, facilitating easy integration into existing manufacturing processes.
• Optimal fastening in plastic substrates with the blunt tip and fully threaded M3.63 size, minimizing material stress and risk of cracking during installation.
• Safe for use in regulated industries with full compliance to RoHS 3 and REACH environmental standards, ensuring no hazardous substances are present.

Professional Applications & Engineering Value

This M3.63 zinc-plated steel TRS tapping screw is engineered to address common challenges in plastic assembly, such as strip-out, vibration-induced failure, and corrosion. The thread-forming (TRS) design with a tri-lobe shank displaces plastic material to create strong, permanent threads without chips, reducing the need for secondary operations. The Torx Plus IP15 drive offers higher torque capability and minimizes driver slippage, which is critical for high-volume production lines. Combined with the zinc-plated finish, it provides reliable performance in electronics enclosures, automotive trim, and consumer appliances, where durability and environmental compliance are paramount. Its compatibility with a standard 1/8" drill bit simplifies hole preparation, streamlining the entire fastening process.

Specification Summary & Compliance

This metric tapping screw features an M3.63 size with an approximate thread pitch of 1.34 mm and a length of 6 mm. It has a pan head style with a standard rounded profile, a blunt tip, and is fully threaded for consistent holding power. Manufactured to precise dimensional standards for reliable performance in plastic applications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety requirements for industrial use.
