Hex Nut Company introduces the use of various screws and nuts:

1. Ordinary external hexagon: It is widely used, and it is characterized by a relatively large tightening force. The disadvantage is that it is installed. There must be enough space to operate, you can use adjustable wrenches or open-end wrenches, or glasses wrenches or more when installing. Wrenches require a lot of operating space.

2. Cylinder head hexagon socket: It is the most widely used of all screws, because it has a relatively large fastening force and is used within. Hexagonal wrench can be operated, it is very convenient for installation. It is used in almost all kinds of structures. The appearance is more beautiful and neat. The disadvantage is that the fastening force is lower than the outer hexagon. In addition, repeated use can easily damage the inner hexagon and make it impossible to disassemble.

3. Pan head hexagon socket: seldom used mechanically, the mechanical performance is the same as above, used under special environment and conditions.

4. Headless inner hexagon: It must be used on some structures, such as the top wire structure that requires a large tightening force, or the place where the cylindrical head needs to be hidden.

Through the above introduction, Hex Bolt Factory hopes that you can simply refer to the content of this article in future use.
