The DeWalt ULTRACON+® SS4 1/4" x 6" Hex Washer Head Screw Anchor – DFM4EUH385 is designed to provide strong and reliable anchoring in concrete and masonry materials. Manufactured from 410 stainless steel, this screw anchor offers excellent corrosion resistance, making it suitable for both indoor and outdoor applications. Engineered with high-low thread technology, the anchor delivers improved holding strength and enhanced gripping performance in base materials such as concrete, brick, and block. The gimlet point tip allows easier penetration and smoother installation into pre-drilled holes. The hex washer head design provides a larger bearing surface that helps distribute load evenly while allowing secure installation with standard hex drivers or sockets. This design also improves torque transfer during fastening.
