S-96817A799 Length 5 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in humid or demanding environments.
• Enhanced torque transmission and reduced cam-out thanks to the Torx Plus IP5 drive, allowing for higher tightening accuracy and tool longevity.
• Secure, permanent fastening in plastic materials through the thread forming (TRS) design, which creates strong mating threads without pre-tapped holes.
• Minimized risk of material cracking due to the blunt tip and fully threaded shank, distributing stress evenly during installation.
• Broad compatibility with standard No. 55 drill bits (0.052" diameter), simplifying hole preparation and reducing assembly time.
• Rounded pan head profile provides a low-profile, finished appearance while preventing snagging in assembled products.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and global market acceptance for your products.

Professional Applications & Engineering Value

This M1.6 x 5mm TRS thread forming screw is precision-engineered to address common challenges in plastic assembly, such as strip-out, vibration loosening, and chemical exposure. The 18-8 stainless steel material offers excellent corrosion resistance, making it ideal for electronics enclosures, automotive trim, and outdoor equipment where moisture is a concern. The Torx Plus IP5 drive ensures reliable torque application, reducing the risk of driver slippage and damage to delicate plastic components. By using a thread forming (TRS) design, the screw cold-forms threads in the plastic, resulting in higher pull-out strength and resistance to back-out compared to thread-cutting alternatives. This combination of fully threaded blunt tip and rounded pan head provides a secure, flush finish that maintains integrity in thin-walled plastic applications, enhancing product durability and assembly efficiency.

Specification Summary & Compliance

This metric screw features an M1.6 size with an approximate thread pitch of 0.64 mm and a length of 5 mm, manufactured to standard dimensional tolerances for consistent performance. The thread forming (TRS) tapping method and right-hand thread direction comply with industry-accepted practices for plastic fastening. It is designed for use with a No. 55 drill bit (0.052" diameter) to ensure proper hole fit. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for hazardous substances.
