Process and characteristics of heavy hex nuts
Heavy duty hex nuts are screw caps that are bolted or screwed together to secure the part. So what is the process of heavy hex nuts? What are the characteristics of heavy hex nuts? Let me talk about the craftsmanship and characteristics of the heavy-duty hex nuts. I hope to help everyone.
Heavy hex nut process
The nickel-phosphorus-plating process for high-strength bolts and nuts consists of three parts. The first part is the pretreatment process, including heavy hex nut plating, manual deoiling, immersion degreasing, pickling, electric activation and visual inspection before the flash nickel plating process; the second part is the electroless nickel plating process. The third part is the post-treatment process, including hydrogen displacement heat treatment, polishing and waste testing. These are the plating processes for these hex nuts.
Heavy hex nut features
Easy to install; integrity; no gasket required; easy to disassemble; reusable medium carbon steel as finished material. The connection structure is simple, the mechanical performance is good, the detachable, anti-fatigue, and no looseness at the time of dynamic loading. This is a promising way to connect.
The heavy-duty hex nut is the nut of the special wrench used for tightening, resulting in a large and controlled pre-tension of the bolt, through which the pre-stress of the same size is applied to the joint. Under the action of the pre-pressure, there will be more friction along the surface of the connector. Obviously, as long as the axial force is less than the frictional force, the part will not slip and the connection will not be broken. This is the principle of a heavy hex nut connection.
The above is about the process and characteristics of heavy-duty hex nuts. I hope everyone can understand the process and characteristics of heavy-duty hex nuts.
