Key Features & Benefits at a Glance

  • Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding environments
  • Excellent thread-forming capability creates strong, permanent threads in plastic materials without pre-tapping
  • Optimized for plastic applications with blunt tip design to prevent material cracking and ensure secure fastening
  • Full threading along the 12mm length provides maximum holding power and uniform stress distribution
  • Easy installation and removal with No. 2 Phillips drive that prevents cam-out and reduces tool slippage
  • Precision compatibility with standard 3.75mm drill bits for quick, accurate installation every time
  • Rounded pan head design offers low-profile appearance while preventing surface damage during tightening

Professional Applications & Engineering Value

These M5 TRS tapping screws deliver exceptional engineering value in plastic assembly applications where traditional fasteners fail. The thread-forming technology eliminates the need for separate tapping operations, creating strong internal threads that resist loosening under vibration and thermal cycling. Made from zinc-plated steel, these screws provide reliable performance in electronic enclosures, automotive trim components, and consumer products where plastic fastening demands precision and durability. The 2.24mm thread pitch and fully threaded design ensure maximum engagement in various plastic densities, while the Phillips drive system enables efficient high-volume installation without specialized tools.

Specification Summary & Compliance

This metric TRS tapping screw features M5 diameter with 12mm length and 2.24mm approximate thread pitch, manufactured to precise dimensional standards for consistent performance. The product meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. Engineered for use with 3.75mm drill bits, these thread-forming screws provide reliable fastening in plastic materials without additional preparation, delivering industrial-grade performance with full regulatory compliance.
