The countersunk hexagon bolt is often used in machinery, which has the advantages of easy fastening, disassembly and not easy to slide angle. The hexagon wrench is generally a 90 ° bend, one end of the bend is long and the other side is short. When the short side is used to bolt, holding the long side can save a lot of force and tighten the bolt better. The long end is divided into round head (hexagonal cylinder similar to a ball) and flat head. The round head can be easily inclined in and disassembled, and some parts which are not convenient for the lower wrench can be installed. The manufacturing cost of the outer hexagon bolt is much lower than that of the inner hexagon bolt. The screw head of the outer hexagon bolt (the force position of the wrench) is thinner than that of the inner hexagon bolt, so the inner hexagon bolt can not be replaced in some narrow places. In addition, the machine with low cost, low dynamic strength and low precision generally adopts external hexagon bolt. The countersunk head hexagon bolts are mostly used in the parts where the surface is required to be flat or smooth, and most of them are countersunk bolts, which are embedded in the parts. It looks quite beautiful.
