Daggerz Self-Drilling Metal Screws with Washer are built for strength, speed, and corrosion resistance in demanding metal-to-metal applications. Featuring a hex washer head and constructed from hardened 410 stainless steel, these screws combine high drilling performance with added protection from the Dagger-Guard coating. They’re ideal for projects that require both corrosion protection and drilling into heavy-gauge steel.

Each screw includes a bonded sealing washer to provide a tight, weather-resistant seal, helping protect against leaks in outdoor and exposed applications. Whether you’re installing metal roofing, steel framing, or structural panels, Daggerz fasteners get the job done with efficiency and reliability.

Key Features:

• 410 stainless steel construction offers strength and drillability for harder substrates
• Dagger-Guard coating enhances corrosion resistance for long-term durability
• Hex washer head allows high torque drive and a secure fit
• Bonded sealing washer helps prevent water intrusion in exterior applications
• Self-drilling tip eliminates the need for predrilling into most metals

Applications:

• Steel framing and structural steel connections
• Commercial roofing and siding systems
• HVAC ducting and support installations
• Outdoor enclosures, equipment, and metal buildings
• Other light and heavy-gauge metal-to-metal fastening projects

Installation Notes:

• Designed for metal-to-metal connections in steel up to 0.210" thick
• Use with a hex socket driver for best performance
• Install until the washer is compressed to create a weather-tight seal
• Avoid overtightening to preserve washer integrity and fastener performance
