1/4 in.-20 x 3 in. Dril-Flex® Undercut-Flat-Head Coarse-Thread Drill-Point Stalgard-Coated Structural Screws (500 Pack) | DEW-DFSEBL330

DEWALT's 1/4 in.-20 x 3 in. Dril-Flex® Undercut-Flat-Head Coarse-Thread Drill-Point Stalgard-Coated Structural Screws are coated with Stalgard®, offering corrosion resistance for both interior and exterior projects. These screws are engineered to minimize material splitting and stripping, supporting efficient installation and long-term durability. They are suitable for general construction, structural assemblies, and metal-to-metal fastening where strength, precision, and weather resistance are critical.

• Dual heat treated self-drilling tapping screws that provide the strength, ductility and resistance to embrittlement required for critical applications
• Dril-Flex® drill-point eliminates the need for pre-drilling in thin-gauge steel
• Coarse threads provide strong engagement and vibration-resistant holding power
• Designed for structural and metal-to-metal fastening in demanding construction projects
• Undercut flat head allows screws to sit flush in countersunk applications
