Product Overview
The Hillman Fasteners 376542 Power Pro Flat Head Phillips Drive Concrete Screw is a self-tapping masonry fastener designed for secure attachment into concrete, brick, and block. This carbon steel screw measures 5/16 inches in diameter and 3-3/4 inches in length, featuring a flat countersunk head that allows for flush installation. It utilizes a Phillips drive system, typically a #3 Phillips bit for this diameter. The screw is finished with a blue epoxy coating, also referred to as Blue Perma-Seal or Blue Climaseal, which provides enhanced corrosion resistance, making it suitable for both dry and moist environments, including use with treated lumber. These concrete screws are used for various applications such as securing wood framing, electrical boxes, conduit straps, and brackets to masonry surfaces. Installation requires a pre-drilled pilot hole, and proper embedment depths, usually between 1 inch and 1-3/4 inches, are crucial for optimal holding power.
