Key Features & Benefits at a Glance

  • Superior corrosion resistance with 18-8 stainless steel and black oxide coating, ideal for harsh industrial environments.
  • Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time.
  • Reliable Phillips drive (No. 3) ensures secure engagement and minimizes cam-out during high-torque applications.
  • Fully threaded shank provides maximum grip and uniform load distribution across the entire fastener length.
  • Standard pan head profile offers a low-profile finish with excellent bearing surface for secure fastening.
  • Precision-engineered dimensions (No. 14 x 3/4") ensure consistent performance and interchangeability in sheet metal assemblies.
  • Compliance with environmental regulations including RoHS 3 and REACH, meeting global industrial safety standards.

Professional Applications & Engineering Value

These black oxide 18-8 stainless steel tapping screws are engineered specifically for sheet metal applications where corrosion resistance and structural integrity are critical. The thread forming technology eliminates the need for separate tapping operations, reducing assembly time and preventing metal shavings in sensitive equipment. The combination of Phillips drive and fully threaded design ensures quick installation and superior pull-out resistance, making them ideal for HVAC systems, electronic enclosures, and automotive panels. The pan head style provides a flush finish while maintaining high clamping force, addressing common challenges of vibration loosening and material fatigue in dynamic industrial environments.

Specification Summary & Compliance

This No. 14 x 3/4" tapping screw features inch system measurements with thread forming (Type A/AB) design, right-hand threading, and pointed tip for easy starting. Manufactured to precise dimensional standards with fully threaded configuration for maximum engagement. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial compliance for global supply chain requirements.
