Product Description

The Wej-It Wej-Con concrete screw cuts threads into concrete, hollow block, brick, mortar, and concrete masonry units (CMUs) to provide a secure hold without requiring threaded inserts. The anchor is made of 1022 carbon steel for strength and has a corrosion-resistant blue R-Blocker coating that meets American Society for Testing and Materials (ASTM) B117 standards to resist 1,000 hours of salt spray. The hex washer head has six flat sides that a wrench can grip to turn from the side, enabling use when there is no space above the head for a screwdriver. It also has a linear slot for use with a flat-blade driver. The head's washer increases the fastener's bearing surface and distributes the clamping force over a larger area, reducing damage to the fixture being fastened.The twin-lead threads and the fully threaded point cut into the mounting material to secure the screw placement and resist pull-out. The screw includes a drill bit to create the correct size hole for installation. The screw can be removed and reinstalled into the same hole to enable fixture changes or screw replacement.SpecificationsWhat's in the Box?
