Hex flange head concrete screw anchor is made of high-strength medium carbon steel after heat treatment. The anchor body is twisted into a unique and efficient high-low self tapping double external thread shape, which ensures fast and convenient tapping into the pre drilled pilot hole and ensures strong tensile load strength.
Heavy duty concrete screw anchor can be disassembled freely. It is suitable for the screw shaped anchor with medium and high-grade load and rapid rotation design. It has double hardening performance and is very suitable for temporary installation or permanent anchoring to the base structure such as concrete, brick, hollow brick or block.
Before installation and use, it is necessary to drill an installation hole in advance, use hexagon socket, ratchet wheel or torque control impact wrench to screw the concrete screw anchor into the hole by tightening the head, and install it quickly by drilling and driving.Unlike other concrete expansion bolts and fixings, concrete screw anchors can be easily removed so that there is no excess debris in the hole. The product has the characteristics of double hardening body, which improves the durability and reliability of concrete screw anchor installation. The large self tapping feature of this bolt is designed for fast propulsion and high performance loading capacity because the thread is formed on the substrate during installation. Save time with fixed installation - just drill and drive to simplify the installation procedure. Completely removable and reusable.
Unique design and patented thread form ensure high performance with relatively small hole diameter.The non expansion function ensures a low risk of damage to the substrate and is ideal for loading applications installed near the edges and adjacent anchors. It can also be installed and used in places without cracks and cracks in concrete. It is also suitable for standard and reduced buried depth sites. Different head types are suitable for a variety of use sites.
