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 strip-resistance thanks to the T8 Torx drive, ensuring secure fastening and longer tool life.
  • Reliable thread forming in plastics using the TRS design, which creates strong, permanent threads without pre-tapping.
  • Clean, flush installation with a standard flat head and 90° countersink angle for a smooth, professional finish.
  • Consistent, high-strength performance with fully threaded M2.5 x 6mm metric dimensions and precise 1.12mm pitch.
  • Compliance with strict environmental standards, including RoHS 3 and REACH, for safe and sustainable use.
  • Optimized for plastic assemblies, reducing the risk of material cracking and ensuring durable, vibration-resistant connections.

Professional Applications & Engineering Value

This M2.5 x 6mm T8 Torx flat head tapping screw is specifically engineered to address common challenges in plastic fastening, such as stress cracking and thread stripping. The 18-8 stainless steel offers excellent corrosion resistance, making it suitable for electronics, automotive components, and outdoor equipment. Its TRS thread forming design displaces plastic material to form robust, load-bearing threads without chips, enhancing pull-out strength and vibration resistance. The T8 Torx drive provides superior torque control, minimizing cam-out and ensuring consistent clamping force in high-volume assembly lines. This combination of material durability and precision threading delivers reliable performance in demanding industrial applications.

Specification Summary & Compliance

This screw features metric M2.5 size with 6mm length, 1.12mm approximate thread pitch, and a standard flat head profile. It is manufactured to precise dimensional standards for reliable fit and function. 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 global markets. The thread forming (TRS) design is optimized for use in plastics, requiring no pre-tapped holes and providing strong, durable threads.
