Generally, hanging ring bolts do not undergo surface treatment, but according to the requirements of use, they can be passivated by galvanizing, chromium plating and other surface treatment. Ring Bolts Surface Treatment Dehydrogenation should be carried out immediately after galvanizing.
As a standard fastener, ring bolt is widely used in mechanical and electrical products. Its main function is lifting load. Ring screw lifting heavy objects, its use is very convenient, but if improper use, such as the location of the lifting screw hole reserved inappropriate, making the center of gravity of the object in the lifting process seriously deviate from the plane of the ring, there will be serious security risks. Thread inspection is carried out with thread gauge and smooth limit gauge or universal energy tool.
Bolts and Screws play an important role in industrial manufacturing. As long as there is industry on the earth, the function of screw will always exist. For thousands of years, screw is an important invention in people’s production and the crystallization of people’s wisdom. In the field of application, screw is the first invention of human beings. And the ring screw has special function and effect because of its special style, which provides convenience and great contribution to the manufacturing process of human machinery. Although the screw is simple in structure, it is easy to use and low in cost. It plays an important role in all walks of life.
