  • Efficient thread forming with AB type tapping method creates strong, reliable threads in sheet metal without pre-tapping.
  • Flush, professional finish thanks to the 82° countersink angle and undercut flat head design that sits seamlessly in materials.
  • High thread engagement with 42 TPI and fully threaded design provides maximum holding power in thin sheet metal applications.
  • Optimized for precision assembly with No. 0 Phillips drive and pointed tip for accurate placement and reduced cam-out.
  • Reliable material compatibility with a 0.0635" drill bit size, ensuring clean installation in sheet metal up to 0.025" thickness.
  • Environmental and regulatory safety through RoHS 3 and REACH compliance, meeting global standards for industrial use.

Professional Applications & Engineering Value

These No. 1 Phillips flat head tapping screws are engineered to address common challenges in sheet metal assembly, such as material stripping and corrosion. The 18-8 stainless steel offers excellent resistance to rust and oxidation, while the thread forming (AB type) method displaces material to create robust, vibration-resistant threads without chips. The fully threaded design and 82° countersink angle ensure a secure, flush fit, minimizing protrusions in tight spaces. Ideal for HVAC, electronics enclosures, and automotive panels, these screws reduce installation time and enhance structural integrity, making them a reliable choice for industrial fastening applications demanding precision and durability.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.073" and length of 3/16". It features a flat head with undercut profile, No. 0 Phillips drive, and right-hand threading for consistent performance. Manufactured to precise tolerances, it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring safety and environmental responsibility in industrial use.
