Ring Bolts Introduction
The ring bolt is a commonly used mechanical connection component. It is made of carbon and its surface has been whitened. The head of the bolt features a hook, and it is used for lifting, towing or fixing loads. Surface treatment: Whitening treatment is a common surface treatment process, usually carried out by applying chemical agents to the surface of the bolt to give it a silver-white luster. This not only enhances the appearance of the bolt but also improves its corrosion resistance to a certain extent. Specifications: The thread specifications are diverse, including M3, M4, M5, M6, M8, M10, M12, etc., which can meet different load-bearing requirements and installation requirements. Application fields: It is widely used in industries such as machinery, ships, power, and construction, for lifting equipment and fixing components, etc.
