[0002] A bolt is a mechanical part, a cylindrical threaded fastener fitted with a nut. It consists of a head and a thread. By spraying a corrosion-resistant coating onto the surface of the bolt, it can achieve a corrosion-resistant effect and thus become a corrosion-resistant bolt.

[0003] The corrosion-resistant bolts currently available on the market have the following problems in actual use:

[0004] 1. Traditional corrosion-resistant bolts, when used in practice, do not have a sealing effect because the gap between the bolt and the bolt is not sealed after the bolt is installed inside the bolt hole. External dust or dirt may enter through this gap, which will make it more difficult to disassemble the bolt and make it inconvenient to use.

[0005] 2. Most corrosion-resistant bolts are made of a single piece of material, consisting of a bolt and a head, and are not removable. When the bolt wears out after prolonged use, the entire bolt must be replaced, resulting in high costs. Utility Model Content

[0006] The purpose of this invention is to provide a bolt with a corrosion-resistant sealing structure to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: A bolt with a corrosion-resistant sealing structure includes a bolt head and a bolt shank.
