Recently I saw a post on the Internet. The netizen said that he saw a lot of blueprints on the Internet and found that almost all the designs used hexagon socket screws. They were very puzzled. Why are engineers so keen to use socket screws? china machine
If you look closely, you will find that 99% of the assembled furniture bought in the evening is a hexagon. , The outer head of the screw head of the Allen screw is round, and the middle is the recessed hexagon. The advantages of such a structure are obvious.
1, to withstand greater loads. It has six force surfaces and it is more reliable than a two-faced flat head screw and cruciform screw. china machine
Note: The material of the hexagon socket bolt is generally made of stainless steel, carbon steel, alloy steel, and other types of screw material basically no difference, the higher the performance level, the greater the strength, the choice of screws must be selected strictly in accordance with the use requirements Screws with a suitable performance level have different grades and prices are different.
2, can bury the handle. That is, the entire nut is sinking into the interior of the workpiece, which keeps the surface of the workpiece flat and beautiful.
3, easy to install. Compared to the hexagonal screws, the hexagon socket is suitable for more assembly occasions, especially narrow ones. Therefore, it is easy to assemble and maintain, and debugging is also convenient. china machine
4, not easy to disassemble. We usually use tools such as live spanners, screwdrivers, and wrenches. The special hexagon wrench must be used to remove the hexagon socket bolts. Therefore, it is not easy for most people to disassemble. This is also an advantage. Of course, if you are struggling, you can design a variety of grotesque structures. The problem is that special wrenches can be manufactured.
With regard to this wrench problem, some netizens said that since the hexagon socket bolts have the advantage of strength, they are designed as counterbore holes. It is very difficult to screw them out if slipping, and the outer hexagon bolts have a common tool to do. Why is it not designed as the following shape? china machine
As we all know, the screws on the external hexagon are exposed. The wrench needs a certain amount of space to twist it. The required counterbore is large or prominent. The hexagon socket needs a small counterbore. When the space is not considered, the hexagonal socket is basically a tasteless one.
Therefore, what kind of screw applications, it depends on the use of occasions. china machine
