  • Drive: Unslotted drive (no access slot) for broad, high-torque contact and reduced cam-out
  • Point: #3 point designed for rapid penetration into metal
  • Size: 5/16" diameter, 12 threads per inch (5/16-12), 1-1/2" long
  • Material/Finish: Steel with zinc plating for corrosion resistance
  • Feature: Serrated washer under the head to improve bite and seating stability
  • Applications: Ideal for fast assembly of metal panels, enclosures, HVAC components, and other metal-to-metal connections

Note: For best results, use with compatible materials and a suitable power driver. Confirm compatibility with your substrate thickness and apply appropriate installation torque to prevent damage.
