Self-Drilling Metal Screws

DeWalt Bi-Flex™ Phillips Pan Head Self-Drilling Screws are engineered for superior performance in metal-to-metal applications. These fasteners feature a self-drilling point that eliminates the need for pre-drilling, helping save time on the job. Designed with a hardened steel shank and Bi-Flex™ corrosion-resistant coating, they provide durability and strength in harsh environments. Ideal for HVAC, electrical, and general metal construction projects, these screws deliver consistent drive...

DeWalt Bi-Flex® Self-Drilling Metal Screws are engineered for reliable, high-performance fastening in metal-to-metal applications. Whether you're installing steel framing, metal roofing panels, or structural decking, these hex washer head screws deliver consistent drive, secure holding power, and long-lasting durability. Manufactured with precision-formed drill points (#2, #3, and #5), DeWalt Bi-Flex® fasteners eliminate the need for pre-drilling—saving time on job sites. Each screw is coated...

DEWALT Dril‑Flex® Self‑Drilling Structural Screws are dual heat‑treated tapping fasteners engineered for reliable steel‑to‑steel connections in demanding building‑envelope and light‑structural applications. A high‑hardness #2–#5 drill point with lead threads speeds drilling and tapping, while a lower‑hardness load‑bearing section improves ductility and reduces susceptibility to hydrogen‑assisted stress corrosion cracking versus case‑hardened alternatives. Stalgard® and Stalgard® SUB coatings...

Dril-Flex® Self-Drilling Structural Screws combine dual heat treatment with a self-drilling, self-tapping design to deliver the strength, ductility, and resistance to embrittlement required for critical connections. The Phillips undercut flat head seats flush where clearance matters and provides a clean, low-profile finish. Stalgard® coating improves corrosion resistance and galvanic compatibility in dissimilar-metal applications, while the hardened drilling point and lead threads speed...

Drilit® self-drilling fasteners eliminate separate drilling and tapping for faster, more economical installations. This Extended Drilling Capacity variant uses higher-capacity drill points (#5) to penetrate thicker steel in a single pass. A hex washer head provides a stable bearing surface and positive drive, while Stalgard® / Gray Stalgard® finishes deliver proven corrosion resistance (ASTM B117 ~1,000 hours). Select sizes are offered with EPDM bonded sealing washers for weather-tight...

Drilit® self-drilling fasteners eliminate separate drilling and tapping for faster, more economical installations. This variant pairs a hex washer head with an EPDM bonded sealing washer to create a reliable, weather-tight seal under metal panels and trims. Available with Stalgard® and Gray Stalgard® corrosion-resistant finishes (typically no red rust after ~1,000 hours per ASTM B117), these screws deliver durable performance in exterior and mixed-material assemblies. Gray Stalgard® is also...

Drilit® self-drilling fasteners eliminate separate drilling and tapping for faster, more economical installations. The hex washer head provides positive drive and bearing surface for reliable seating, while the integrated self-drilling point speeds penetration in steel and other common substrates. Available with Stalgard® and Gray Stalgard® corrosion-resistant finishes (ASTM B117 ~1,000-hour salt-spray performance), and in select sizes with EPDM bonded sealing washers for a weather-tight seal....
