Structural & Specialty Screws

DEWALT Dril-Flex® Phillips Wafer Head screws combine a hard, self-drilling point with a tougher load-bearing shank to deliver fast drilling, strong clamp load, and resistance to hydrogen-assisted stress corrosion cracking. The low-profile wafer head offers a wide bearing surface that helps reduce pull-through in thin-gauge metal panels and attachments, while the #2 Phillips drive provides familiar, precise control. Stalgard® coating improves corrosion resistance and galvanic compatibility...

The Bi-Flex® Bi-Metal Self-Drilling Structural Screw combines the superior corrosion resistance of 300 series stainless steel with the drilling efficiency of carbon steel. Featuring a Phillips pancake head for a low-profile finish, these screws are ideal for steel-to-steel, aluminum-to-steel, aluminum-to-aluminum, and wood-to-steel connections. The Stalgard® GB coating enhances galvanic compatibility in dissimilar metal applications, including those involving aluminum. Designed for high...

DEWALT Bi-Flex® Phillips Flat Head with Wings screws are bi-metal self-drilling structural fasteners designed for efficient wood-to-metal installations. Featuring a corrosion-resistant 300-series stainless-steel shank and head paired with a hardened carbon-steel drill point, these screws deliver long-lasting performance in outdoor and high-moisture environments. The integrated cutting wings create clearance holes through wood or composite materials before breaking off as the drill point...

DEWALT Bi-Flex® Phillips Undercut Flat Head Bi-Metal Self-Drilling Structural Screws deliver the corrosion resistance of 300-series stainless steel with the drilling efficiency of hardened carbon steel. Designed for steel-to-steel, aluminum-to-aluminum, aluminum-to-steel, and wood-to-steel connections, these fasteners feature Stalgard® GB coating for enhanced galvanic compatibility in dissimilar metal applications and increased protection in outdoor or high-moisture environments. The undercut...

Tap-Flex® Thread-Forming Structural Screws are engineered for high-performance fastening in demanding structural and curtain wall applications. Designed to replace traditional nut and bolt assemblies, these dual heat-treated self-tapping fasteners provide the strength, ductility, and corrosion resistance required for long-term reliability. Featuring the patented E-Form® segmented thread profile, Tap-Flex® screws reduce drive torque, improve installation efficiency, and form threads that ensure...

TapFast fasteners are engineered for attaching light-gauge metal panels (up to 18 ga) to wood frame structures. Featuring a hex washer head paired with an aluminum EPDM bonded sealing washer for a reliable, weather-tight seal, TapFast delivers strong pull-out performance in wood while easily penetrating multiple panel thicknesses. The high-low thread design improves driving efficiency and holding power, and the Stalgard coating provides superior corrosion resistance versus standard zinc...
