Designed with a hex cupped washer head and bonded EPDM sealing washer, this screw provides secure clamping force and a reliable weather-tight seal. The self-drilling tip eliminates the need for pre-drilling, helping crews move faster on steel-to-steel applications.

Key Features

  • Self-Drilling Point: Drives directly through metal panels into steel framing.
  • ZXL Protective Coating: Enhanced corrosion resistance for long-term performance.
  • Hex Cupped Washer Head: Delivers strong clamping pressure and secure panel seating.
  • Bonded EPDM Washer: Maintains a watertight seal against moisture intrusion.

Common Applications

  • Metal Roofing Systems: Attach panels to structural steel.
  • Commercial Buildings: Secure roofing and siding assemblies.
  • Agricultural Structures: Install panels on barns and pole buildings.
  • Industrial Facilities: Reinforce steel-to-steel connections.
  • Retrofit Projects: Replace worn or corroded fasteners.

Installation Tips

  • Use a Magnetic Nutsetter: Maintain alignment during driving.
  • Apply Steady Pressure: Allow the drill point to penetrate fully.
  • Tighten Until Washer Seats: Compress gasket evenly without over-driving.
