The ST Fastening 1/4 x 4 inch Self-Drilling HWH Steelbinder Metal Roofing Screw is engineered for long-reach fastening in metal-to-metal roofing applications.

  • Integrated Sealing Washer: Helps create a watertight seal at the fastening point.
  • Hex Washer Head: Provides strong torque transfer and even load distribution.
  • Electro-Galvanized Finish: Enhances corrosion resistance for outdoor use.

Common Applications

  • Metal Roofing Systems: Secure panels to steel purlins and framing.
  • Commercial Buildings: Install long fasteners through insulated assemblies.
  • Agricultural Structures: Attach roofing panels to structural steel.
  • Industrial Facilities: Reinforce heavy-duty metal connections.
  • Roof Retrofits: Replace worn fasteners with extended-length screws.

Installation Tips
