The DEWALT Ultracon SS4 1/4 in x 3-1/4 in hex washer head concrete screw anchor (DFM4EUH345) is supplied for mechanical fastening into concrete, solid masonry, and block substrates used in structural and non-structural assemblies. The anchor is made from 410 stainless steel to support corrosion resistance in indoor and outdoor service environments where moisture exposure is present. The high-low thread profile supports controlled cutting into base material and maintains consistent holding values under vibration and service load conditions. The hex washer head drive interface supports torque transfer with standard hex drivers and reduces cam-out during installation.
