[0002] A bolt is a mechanical part, a cylindrical threaded fastener used in conjunction with a nut. It is a type of fastener composed of two parts: a head and a screw rod. It needs to cooperate with a nut to be used for firmly connecting two parts with through holes. This connection form is called bolt connection. If the nut is screwed off the bolt, the two parts can be separated. Therefore, bolt connection belongs to detachable connection.

[0003] During the long-term use of existing bolts, due to the contact between water vapor in the air and the bolts made of metal materials, the surface of the bolts is extremely prone to rusting. When the bolts need to be disassembled, the notches on the surface of the bolt caps at the tops of the bolts are blurred due to corrosion, affecting the disassembly effect. Therefore, it is necessary to provide a high-strength bolt that is convenient to disassemble to solve the above problems. Content of the Utility Model
