When you need a robust and efficient metal-to-metal fastening solution, the Daggerz Self-Drilling Metal Screw with Hex Head and Dagger-Guard Coating delivers. The self-drilling point eliminates the need for pilot holes while the hex washer head provides strong driving stability and a flush, secure finish. With fine threads to maximize holding power and a corrosion-resistant Dagger-Guard finish that passes a 1,000-hour salt-spray test, this screw is ideal for demanding applications where performance and durability matter.

Key Features

• Self-Drilling Point: Eliminates the need for pre-drilling by cutting directly into metal substrates for faster installation.
• Hex Washer Head: Offers better driving control and a tight, flush finish for secure metal connections.
• Fine Threads: Provide high pull-out strength and solid engagement in steel and other metals.
• Dagger-Guard Coating: Corrosion-resistant finish rated for 1,000-hour salt spray exposure. Suitable for indoor and exterior applications.
• Available in Multiple Sizes: Choose from a range of diameters and lengths to suit a wide variety of structural and fabrication jobs.

Applications

• Attaching metal panels, purlins, or brackets to structural steel framing without pre-drilling.
• Installing metal roofing, siding, or cladding where strength and corrosion resistance are essential.
• HVAC, sheet metal fabrication, and general steel construction applications.
• Interior and exterior construction jobs where durability and fast installation matter.

Installation

1. Select the appropriate length and diameter to ensure the point fully penetrates the steel and the threads engage properly.
2. Use a power driver with a hex driver bit (typically 5/16") and set torque to avoid overdriving or stripping.
3. Drive the screw perpendicular to the metal surface until the hex washer head sits flush.
4. Verify that the Dagger-Guard coating is appropriate for the environmental conditions of the installation site.
5. Follow all spacing and fastener pattern guidelines to maintain structural strength and compliance with building codes.
