1/4 X 5 CONCRETE SCREW (SLOTTED INDENTED HEX WASHER HEAD) BLUE FINISH

Tapcon®-style concrete screws are driven into concrete, brick, and block, and serve as anchors. These concrete screws tap threads into a predrilled hole. The concrete screw has alternating raised and lowered threads with sharp cut notches that offer essential grip and stability. A blue xylan coating offers longer life and enables easier driving.
