Product Details：
The ring nut is a fastening part used for fixed assembly in fields such as mechanical equipment, molds, chassis and ships. It is used in conjunction with bolts or screws through the inner thread to play a role in connection and reinforcement.
Ring nuts usually have threads and can be fixed by drilling holes according to different specifications. They are suitable for loading and unloading of lifting machinery and equipment as well as general fastening scenarios. Its standard specification is M8-M100×6, and the materials are mostly 20 steel or 25 steel. It needs to undergo forging and normalizing treatment, and the surface treatment is generally galvanizing passivation or chromium plating.
Application scenarios：
It is widely used in industrial fields such as ports, power, shipbuilding, construction, and automobile manufacturing to ensure the tight connection and safe fixation of mechanical equipment components.
Material：
The material of the ring nut includes 20/25 carbon steel and 304 stainless steel. It needs to undergo integral forging and normalizing treatment, with a grain size of no less than grade 5. The surface can be treated with galvanization, chromium plating or passivation. The threaded interface must be inspected by a dedicated gauge and marked with specifications and load-bearing parameters. When in use, the load must not exceed the rated limit. If the ring part is deformed, it should be scrapped immediately. For 45° lifting, a 锪 hole should be provided to ensure the support surface is in close contact. Special steel may have reduced ductility after heat treatment and there is a risk of overload fracture.
