Description

Daggerz Self-Drilling Metal Screws with Wings are designed to tackle demanding wood-to-metal applications with speed and precision. These screws feature a sharp self-drilling point and winged design that prevents wood splitting and ensures smooth penetration through wood and into steel framing. As the wings snap off upon hitting metal, the screw continues cleanly into the steel without interference or damage to the threads.

The ACQ Dagger Pro Coating delivers exceptional corrosion resistance, making these screws suitable for use in treated lumber and exterior environments. With a flat Phillips head for a flush finish, these screws are ideal for professional contractors and DIYers working on framing, sheathing, decking, and other wood-to-steel fastening jobs.

Key Features:

  • Self-drilling point eliminates the need for predrilling, reducing labor time
  • Winged design clears excess wood and breaks off before entering metal
  • ACQ Dagger Pro Coating protects against corrosion in treated lumber and outdoor use
  • Flat head with Phillips drive for a clean, flush installation
  • Suitable for fastening wood to steel in a range of construction applications

Applications:

  • Wood-to-metal framing connections
  • Treated lumber to steel fastening
  • Sheathing and decking over metal
  • Residential, commercial, and agricultural building projects
  • Indoor or outdoor environments where corrosion resistance is required

Installation Notes:

  • Use a Phillips drive bit and power drill for efficient installation
  • Position screw straight for accurate penetration through both materials
  • No predrilling required for most applications
  • For best results, drive until the head sits flush with the wood surface

    The Right Point for Every Project

    Different point types pierce various materials. Standard points handle light- to medium-gauge metal, long points tackle thicker steel, self-piercing points work well in wood or thin metal and winged points clear softer layers before drilling harder substrates, ensuring faster, cleaner and secure installations.
