Many customers ask such questions: How to choose the materials of bolts and nuts? Obviously, such customers do not know much about the raw materials of nuts. If you have any questions, please call our sales phone in general!
The differences between the mechanical requirements of bolts and nuts are:
① The mechanical function of the nut mainly depends on the hardness of the nut, the height of the nut, and the wall thickness of the nut. Therefore, the requirements for data are not high. Of course, if the nut has tolerance requirements, higher-level data should also be used, such as chemicals Fasteners and nuts have requirements for resistance, which sets higher-level information.
② The plasticity target required by the bolt, the higher the functional level, only the higher-level data can be reached. The lower-level data can only reach the strength requirements after reducing the tempering temperature, but it cannot meet the requirements of plasticity and resistance. In the fastener testing The brittle fracture was judged as unqualified. Steel structural bolts also have a higher tensile strength in order to ensure the plastic resistance of the bolts.
