When selecting the specifications and dimensions of bolts and nuts, the following aspects need to be considered: Load requirements: According to the load borne by the connector, determine the strength level of the bolts and nuts required. In general, the greater the load, the higher the level of bolt and nut strength required. Connector thickness: Select the appropriate bolt and nut length according to the thickness of the connector to ensure a solid connection. In general, the bolt length should be greater than or equal to the total thickness of the connector plus the thickness of two screw washers. Thread type: Select internal or external thread as needed. Internal threads are often used for bolts and external threads for nuts. Select thread series as required, such as M series (metric thread) or UNC/UNF series (inch thread). Environmental conditions: According to the characteristics of the use of the environment, the selection of corrosion resistance, high temperature resistance, vibration resistance and other special materials or coatings of bolts and nuts to ensure its long-term performance. Standard specifications: refer to national standards or industry standards, select the specifications and sizes of bolts and nuts that meet the requirements. Generally used standards are GB/T (national standard), ISO (international standard) and so on. When selecting bolts and nuts, you are advised to refer to professional manuals, related standards, and consult professionals to ensure that the selected bolts and nuts meet engineering and safety requirements.
