8.8 10.9 12.9 Grade High Strength Black Oxidation Carbon Steel Hex Nuts

High strength nut features:


(1) easy to install; Integrity; No washing machine is needed; Easy to disassemble; Reusable medium carbon steel is used in the manufacture of materials. Simple connection structure, good mechanical properties, disassembly, anti-fatigue, no loosening under dynamic load. This is a very promising connection method.


(2) High strength nuts are used to tighten special wrench nuts so that the bolts generate large and controlled pretension through the nuts and buffer plates, applying the same size of pretension on the joint. Under the action of preload, there will be more friction along the connector surface. Obviously, as long as the axial force is less than the friction force, the part will not slip and the connection will not be broken. This is the principle of the high strength nut connection.


High strength nuts are steels used for fasteners and have high interchangeability produced by the cold heading process. Because it is formed by metal plastic processing at room temperature, the deformation of each part is large and the deformation rate is high. Therefore, the performance requirements of high strength nut raw materials are very strict. Buy high strength nuts for professional manufacturers to buy, our products are rich, quality, is a reliable good product
