Key Features & Benefits at a Glance

  • Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in harsh industrial environments.
  • Enhanced torque transfer and reduced cam-out thanks to the T15 Torx drive, providing reliable and efficient installation.
  • Secure, vibration-resistant fastening in sheet metal due to the Tri-Lobe shank design that forms strong, permanent threads.
  • Easy alignment and consistent seating with a standard pan head profile, distributing clamp load evenly.
  • Quick installation in coarse-thread applications using UNC 6-32 threading, ideal for a variety of sheet metal thicknesses.
  • Full thread engagement for maximum holding power along the entire 3/8" length, reducing the risk of loosening.
  • Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use.

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered to address common challenges in sheet metal fabrication, such as material fatigue and fastener failure under stress. The thread forming (Type CA) design with a Tri-Lobe shank creates precise, durable threads without cutting, which preserves the integrity of the metal and provides excellent resistance to vibration loosening. Combined with a T15 Torx drive, they enable high-torque applications without stripping the drive, making them ideal for assembly lines and maintenance in automotive, HVAC, and electronics enclosures. The blunt tip and coarse UNC thread ensure easy starting and reliable performance in pre-drilled holes, reducing installation time and improving overall efficiency in industrial settings.

Specification Summary & Compliance

This screw features a No. 6 size with 6-32 UNC coarse threads, conforming to standard inch measurements for precise fit. The thread forming tapping method and fully threaded design ensure consistent performance in sheet metal applications, with a recommended drill bit size of No. 32 (0.116" diameter). All specifications adhere to industry norms for dimensional accuracy. Additionally, these screws are fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for industrial use.
