It should be noted that although external hexagonal bolts have various advantages, they also have limitations in certain situations. For example, they cannot be used on thin-walled parts or in situations where they are subjected to impact, vibration, or alternating loads. If they exceed a certain length, they do not have full threads, tightening tools are not easy to match, and they are easy to screw and replace. A professional wrench should be used for disassembly, which is not easy to disassemble normally.

    External hexagonal bolts are a common type of mechanical fastener, mainly used for connecting and fixing mechanical equipment.

    External hexagonal bolts are commonly used for:

    1. Connecting components: The outer hexagonal bolt fixes multiple components together through the action of torque, forming a whole.

    2. Load bearing: Due to its high-strength design, the outer hexagonal bolt can withstand large loads and shear forces, and is not easy to break or loosen, ensuring the firmness of the connection.

    3. Easy installation: No special fixtures or tools are required during installation, it can be completed with a wrench or wrench, and the installation speed is fast, which can improve production efficiency.

    4. Wide application range: External hexagonal bolts are suitable for various connection situations, such as heavy machinery, construction, and bridge engineering, and can meet various connection requirements.
