The Dewalt DFSEBL340 Dril-Flex Self-Drilling Structural Screw is an engineered fastener designed for critical metal-to-metal applications. These screws are dual heat-treated to ensure the necessary strength and ductility required to prevent embrittlement. They solve the problem of needing a reliable, high-performance structural anchor that can self-drill and tap into steel efficiently.

• Durability: Features a Stalgard coating and dual-hardened alloy steel construction to resist corrosion and structural failure in demanding environments.
• Efficiency: The self-drilling design with a #4 point allows for rapid installation, eliminating the need to pre-drill pilot holes in many structural steel applications.
• Compatibility: The 1/4 in-20 TPI thread specification and #3 Phillips Undercut Flat Head ensure compatibility with standard structural tooling and a flush finish.

This fastener is best suited for structural engineers, steel fabricators, and commercial construction crews requiring secure, high-integrity connections in metal framing or other critical load-bearing assemblies.

• Length: 4 in Nominal Length.
• Thread: 1/4 in-20 TPI.
• Head Type: #3 Phillips Undercut Flat Head.
