Does the special bolt have a unique head design?

Special bolts normally have a unique head layout.
The head layout of special bolts is to satisfy particular application requirements. For example, the head form of a few special bolts is designed for less difficult set up or disassembly, or to offer better stability in specific running environments.
In addition, the top design of special bolts can also be related to their fabric, production manner, or usage environment. For instance, certain special bolts can also use special materials or manufacturing procedures to increase their energy, corrosion resistance, or put on resistance.
Therefore, special bolts commonly have specific head designs to satisfy particular application requirements and utilization environments.
