Key Features & Benefits at a Glance

  • Superior corrosion resistance with 18-8 stainless steel construction, ideal for demanding environments
  • Enhanced torque transmission from the T8 Torx drive, reducing cam-out and tool wear
  • Optimal material displacement through TRS thread forming design, creating strong, vibration-resistant threads in plastics
  • Flush mounting capability with the 90° countersink angle and flat head profile for clean, professional finishes
  • Full-length threading ensures maximum grip and holding power across the entire screw length
  • Reliable installation with blunt tip design that prevents plastic splitting during assembly
  • Regulatory compliance with RoHS 3 and REACH standards for safe, environmentally conscious manufacturing

Professional Applications & Engineering Value

This M2.5 thread forming screw is specifically engineered to address common challenges in plastic assembly applications. The 18-8 stainless steel construction provides excellent corrosion resistance, while the TRS thread forming design creates strong, permanent threads in plastic materials without generating chips. The T8 Torx drive offers superior torque transfer compared to traditional drives, reducing installation time and preventing fastener damage. With its 90° countersink angle and flat head profile, this screw sits flush with surfaces, making it ideal for electronics enclosures, automotive trim components, and consumer products where aesthetics and reliability are paramount. The fully threaded design and blunt tip ensure secure fastening while minimizing stress concentration in brittle plastics.

Specification Summary & Compliance

This metric M2.5 x 5mm tapping screw features standard thread pitch of 1.12mm with right-hand threading and fully threaded shank. Manufactured to precise dimensional standards with a flat head profile and T8 Torx drive compatibility. The screw is designed for use with No. 45 drill bit (0.082" diameter) and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial applications.
