Key Features & Benefits at a Glance

  • Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and long-term reliability.
  • Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs.
  • Flush seating and reduced head protrusion thanks to the 82° countersink angle and undercut flat head profile for smoother finished surfaces.
  • High torque transmission with No. 3 Phillips drive size, minimizing cam-out and ensuring secure fastening in demanding applications.
  • Full-length threading provides maximum grip and holding power across the entire 3/4" length in sheet metal up to 0.025" thickness.
  • Consistent performance with precise Class 2A thread tolerances and 10 threads per inch for reliable engagement and vibration resistance.
  • Environmental and regulatory compliance with RoHS 3 and REACH standards, ensuring safe use in global industrial supply chains.

Professional Applications & Engineering Value

These No. 14 Phillips flat head tapping screws are engineered specifically for sheet metal applications where durability, corrosion resistance, and flush mounting are critical. The 18-8 stainless steel material offers excellent strength and rust resistance, making these screws ideal for HVAC systems, electronic enclosures, and automotive assemblies exposed to moisture or chemicals. The thread forming (Type A) design displaces material to create strong, load-bearing threads without chips, eliminating the need for separate tapping operations and reducing assembly time. The undercut flat head and 82° countersink angle ensure a clean, low-profile finish that minimizes snagging and improves aesthetic appeal in visible applications. These features collectively address common industrial pain points like fastener failure, corrosion-induced downtime, and inefficient installation processes.

Specification Summary & Compliance

This screw features a No. 14 size with 0.242" thread diameter and 10 threads per inch, manufactured to standard Class 2A inch-series tolerances for consistent fit. The Type A thread forming design complies with industry standards for self-tapping fasteners in sheet metal. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety requirements for industrial components.
