Key Features & Benefits at a Glance

  • Superior corrosion resistance with zinc-plated steel construction, ensuring long-term durability in various industrial environments.
  • Efficient thread-forming design eliminates the need for pre-tapping, reducing assembly time and labor costs in plastic applications.
  • Enhanced vibration resistance thanks to the Tri-Lobe shank cross-section, providing reliable, long-lasting fastening under dynamic loads.
  • Easy installation with a Phillips No. 2 drive, allowing for quick, secure driving without slippage in high-volume production settings.
  • Optimized material displacement from the fully threaded, blunt tip design, minimizing stress cracking in plastic components.
  • Broad compatibility with 1/8" drill bits, streamlining the preparation process for consistent, precise hole sizing in plastic assemblies.
  • Compliance with global safety standards including RoHS 3 and REACH, ensuring environmentally responsible and safe usage in industrial applications.

Professional Applications & Engineering Value

Engineered for demanding plastic fastening scenarios, these No. 6 TRS tapping screws address common challenges like material cracking and loosening under stress. The thread-forming Tri-Lobe shank displaces plastic efficiently, creating strong, permanent threads without pre-tapping, which is ideal for high-volume plastic assembly in automotive, electronics, and consumer goods. The zinc-plated steel offers reliable corrosion protection, while the Phillips drive ensures consistent torque application, reducing installation errors and enhancing production line efficiency in industrial fasteners applications.

Specification Summary & Compliance

This screw features a 0.138" thread diameter with approximately 19 threads per inch, right-hand threading, and a 1" length for precise engagement. Manufactured to standard tolerances for thread-forming TRS type screws, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards in industrial use.
