Key Features & Benefits at a Glance

  • Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments.
  • Enhanced torque transmission and reduced cam-out with T15 Torx drive, providing secure installation and minimizing tool slippage.
  • Excellent thread-forming capability in sheet metal without pre-tapping, thanks to the Tri-Lobe shank design that creates strong, reliable threads.
  • High pull-out and vibration resistance from the fully threaded UNC coarse thread design, maintaining secure fastening under stress.
  • Wide compatibility and easy identification with standard No. 6-32 thread size and 1/4" length, fitting common sheet metal assembly requirements.
  • Secure and flush seating with the pan head style, offering a low-profile finish that distributes clamping force evenly.
  • Compliance with environmental and safety standards, including RoHS 3 and REACH, ensuring safe use in various industrial applications.

Professional Applications & Engineering Value

These 6-32 x 1/4" zinc-plated steel tapping screws are engineered to address common challenges in sheet metal assembly, such as stripping, loosening under vibration, and corrosion. The thread forming CA type with a Tri-Lobe shank displaces material to form precise threads, eliminating the need for pre-drilled threads and reducing installation time and costs. The T15 Torx drive ensures high torque application without cam-out, ideal for automated or high-volume production lines. Made from zinc-plated steel, these screws provide durability and resistance to rust, making them suitable for HVAC, electronics enclosures, and automotive components where reliability and RoHS/REACH compliance are critical.

Specification Summary & Compliance

This product features a No. 6-32 UNC coarse thread with a length of 1/4", fully threaded for consistent grip. It adheres to standard dimensional tolerances for thread forming screws, including a blunt tip and right-hand thread direction. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring environmental safety and suitability for industrial use in sheet metal and similar materials.
