Screws have a wide range of uses in people's production and life. How to purchase the standard screw that meets the requirements is very important, otherwise it will cause various problems such as quality problems and high budgetary costs. The difference between the hex screw and the hex socket screw is for everyone to share.
The screws of the hexagon socket head cap screws and the hexagon socket head screws are divided into inner and hexagon socket screws according to the shape of the screw head, and it is irrelevant to the material of the screw and the bearing capacity of the screw.
The screw head of the hexagon socket screw is round, and the hexagon is recessed in the middle, and the hexagonal screw is the hexagonal screw with a hexagonal shape on the side of the screw head. Main differences: Hexagon socket screws are often used on machinery, and have the advantages of being easy to tighten, disassemble, and not easy to slip.
The Allen key is usually a 90° curved curved shape. The bent end is long and short. When using a short side to screw, the long side of the hand can save a lot of force and better tighten the screw. The long end is divided into a round head (hexagonal cylinder like a sphere) and a flat head. The round head can be easily removed and removed, and some parts of the wrench are inconvenient to be installed.
The manufacturing cost of the hexagonal screw is much lower than that of the inner hexagon. Its advantage is that the screw head (the position of the wrench is thinner than the inner hexagon), and some places are not replaced by the inner hexagon. In addition, the cost of the machine is low, the power is small, and the precision of the machine requires less hexagon socket screws than the outer hexagon.
