  • Enhanced load distribution from the 0.52" flange diameter, preventing surface damage and improving joint integrity
  • Thread forming technology creates strong, permanent threads in sheet metal without chip removal
  • External hex/slotted drive provides versatile installation options with common tools
  • Fully threaded design ensures maximum holding power along the entire 3" length
  • Environmental compliance with RoHS 3 and REACH standards for safe industrial use
  • Optimized thread pitch (10 threads per inch) delivers excellent pull-out resistance in sheet metal applications

Professional Applications & Engineering Value

These No. 14 sheet metal tapping screws are engineered specifically for demanding metalworking applications where thread forming technology provides significant advantages over traditional fastening methods. The flanged hex head design eliminates the need for separate washers while providing superior clamping force distribution across the mating surface. The fully threaded construction and pointed tip enable rapid installation in sheet metal up to 0.025" thickness, reducing assembly time while creating strong, vibration-resistant connections. These thread forming screws are ideal for HVAC systems, electrical enclosures, automotive panels, and industrial equipment where reliable fastening in thin-gauge materials is critical.

Specification Summary & Compliance

This No. 14-10 x 3" flanged hex head sheet metal screw features a 0.242" thread diameter with 10 threads per inch in right-hand orientation. Manufactured to precise dimensional standards with Class 2A thread tolerances for consistent performance. The screw requires a 5.5mm (0.2165") drill bit for proper hole preparation. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial applications worldwide.
