Key Features & Benefits at a Glance

  • Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for humid or demanding environments.
  • Enhanced torque transmission and reduced cam-out thanks to the T6 Torx drive, ensuring secure fastening and extended tool life.
  • Clean, flush installation with a standard flat head and 90° countersink angle for a professional finish in plastic assemblies.
  • Strong, reliable thread formation in plastic materials using the TRS thread-forming design, eliminating the need for a pre-tapped hole.
  • Full-length threading (M2 x 8mm) provides maximum grip and holding power along the entire shank for superior pull-out resistance.
  • Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and suitability for various global markets.
  • Simplified installation process with a compatible No. 52 drill bit (0.0635" diameter), enabling precise and efficient assembly.

Professional Applications & Engineering Value

These M2 x 8mm TRS thread-forming screws are specifically engineered to address common challenges in plastic fastening, such as material cracking and weak thread retention. The 18-8 Stainless Steel material offers excellent corrosion resistance, making these flat head screws suitable for electronics, automotive components, and outdoor equipment where moisture exposure is a concern. The T6 Torx drive provides superior torque control compared to traditional drives, reducing the risk of stripping and ensuring consistent clamping force in brittle plastics. With a 0.89mm pitch and fully threaded design, they create strong, permanent threads in plastic substrates, enhancing assembly integrity and longevity while streamlining production with their thread-forming capability that eliminates tapping operations.

Specification Summary & Compliance

This screw conforms to standard metric (M2 x 8mm) dimensions with a right-hand thread and fully threaded shank. It features a standard flat head profile with a 90° countersink angle and is designed for use with a No. 52 drill bit. The product is manufactured to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets stringent environmental and safety standards for industrial use.
