Screws are used to connect two objects. Generally, the head of the screw will protrude from the object's surface. But the Hexagon Socket Countersunk Head Screws will not cause this problem and keep the surface flat after installation. They are often used in machinery, mainly for easy fastening, and easy disassembly, and are not easy to slip. The wrench is generally a 90-degree turning wrench. When screwing with the short side, holding the long side can save a lot of force for you and can play a good tightening role.
Hexagon Socket Countersunk Head Screws will not make the surface of the parts have protrusions after installation. The parts of the fastener have two thicknesses. The so-called thick one means that the thickness of the fastener part is greater than the thickness of the head of the hexagon socket head screw. After the screw is tightened, there are still some threads that do not enter the threaded hole. In this case, the socket head cap screws can be tightened. The screw finish can be zinc plating, hot-dip galvanized, nickel, etc., and we can also follow your drawings or samples to produce non-standard hexagon socket screws.
