PANSIAM Flat Head Countersunk Hi-Lo Concrete Screws #10 x 1-1/4" (Pack of 25 pcs)
This type of concrete screw differs from conventional screws, particularly with its Hi-Low dual-thread system, which features alternating high and low threads to tap into concrete and enhance holding power effectively, enabling installation without the need for plastic or steel anchors.The screw head features a countersunk design engineered to sit flush within the surface of the fastening material (such as wood or thin angle iron) so that the screw head remains level with the workpiece surface, providing a neat finish without obstructing other operations. Installation always requires drilling a pilot hole into the concrete beforehand to the specified size before driving the screw in.
