What is the difference between hexagonal wood screw and hexagon socket wood screw

The difference between the hexagonal wood screw and hexagon socket wood screw is in the screw head. The hexagonal screw head has a hexagonal column shape and a small height; the hexagonal screw head is cylindrical, with a hexagonal hole in the middle, and the same diameter screw , The hex head should be thicker. Two kinds of screws are installed and removed using different tools (common wrench and hex wrench) respectively. The load capacity of the two screws of the same material and the same rib is the same. It is mainly selected according to the requirements of the installation position for the screw head. Where the countersunk head screws are used, it is much more convenient to use hexagon socket screws for tightening, but the depth of the countersunk holes that need to accommodate the screw heads is much greater, and a special hexagon socket wrench is required, which can handle different sizes than ordinary adjustable wrenches. The external hex screw is troublesome; therefore, hex head or internal hex head should be selected according to the specific situation. Commonly used hex head screws and hex head screws use the same thread standard and marking method, that is, M4, M6, M8, M10, M12, M14, seems to use more points.
