S-95893A224 Length 16 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 T15 Torx drive, providing secure fastening and minimizing tool slippage
• Optimal material displacement and strong thread engagement in plastic substrates due to the TRS thread-forming design, creating durable assemblies
• Streamlined installation and flush finish with the standard flat head profile and 90° countersink angle, ideal for aesthetic and space-constrained applications
• Full-length threading for maximum grip along the entire 16mm length, ensuring consistent holding power in plastic materials
• Simplified pre-drilling process requiring only a No. 34 drill bit (0.111"), reducing setup time and improving assembly accuracy
• Compliance with environmental regulations including RoHS 3 and REACH, making them suitable for global markets and sensitive applications

Professional Applications & Engineering Value

These M3.5 x 16mm TRS tapping screws are precision-engineered to address common challenges in plastic assembly, such as material cracking and weak thread retention. The thread-forming (TRS) design displaces plastic material without cutting, creating strong, load-bearing threads that resist loosening under vibration. Manufactured from 18-8 stainless steel, they offer excellent resistance to oxidation and corrosion, extending service life in demanding conditions. The T15 Torx drive ensures high torque application with minimal risk of stripping, while the blunt tip and fully threaded body provide consistent engagement and pull-out strength. Ideal for electronics enclosures, automotive trim, and consumer products, these screws deliver reliable performance in plastic fastening applications where durability and compliance are critical.

Specification Summary & Compliance

This metric flat head screw features M3.5 size with an approximate thread pitch of 1.57 mm and a length of 16 mm, adhering to standard dimensional tolerances for precision fit. The right-hand threaded, fully threaded design ensures uniform load distribution. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances. Designed for use with a No. 34 drill bit (0.111" diameter) and a 90° countersink angle, it meets industry standards for thread-forming screws in plastic materials, providing reliable performance and regulatory assurance.
