Key Features & Benefits at a Glance

  • Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
  • Enhanced torque transmission through the external hex/slotted drive and flanged head design, preventing cam-out and ensuring secure fastening
  • Efficient thread cutting in various materials including aluminum, brass, cast iron, and sheet metal without requiring pre-tapped holes
  • Reliable coarse UNC threading (10-24) provides excellent pull-out resistance and faster installation in soft materials
  • Full threading along the 1" length ensures maximum grip strength and uniform stress distribution
  • Precision compatibility with No. 19 drill bit (0.166" diameter) for optimal hole preparation and thread engagement
  • Industry compliance with ASME B18.6.3 specifications and RoHS 3 environmental standards for guaranteed performance and safety

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional thread cutting performance in challenging applications involving aluminum, brass, cast iron, and sheet metal. The Type F tapping screw design with coarse UNC threading creates precise internal threads while minimizing material displacement and stress concentration. The flanged hex head combined with external hex drive provides superior torque transmission during installation, reducing the risk of head stripping and ensuring consistent clamping force. This makes them ideal for assembly lines, metal fabrication, and equipment manufacturing where reliable fastening and vibration resistance are critical. The fully threaded design maximizes surface contact area, enhancing joint integrity in both thin and thick material sections commonly encountered in industrial settings.

Specification Summary & Compliance

This 10-24 UNC thread cutting screw features Class 2A thread tolerances with coarse spacing, manufactured from zinc-plated steel with a blunt tip and fully threaded shank. The product meets ASME B18.6.3 specifications (where identified as SAE J933) for dimensional accuracy and performance standards. Compliance with RoHS 3 (2015/863/EU) ensures environmental safety and regulatory acceptance for industrial applications worldwide.
