Electric wrench is a handheld electric tool used for loading and unloading threaded connectors. It is widely used in the assembly work of manufacturing industries such as automobiles, tractors, electric motors and appliances, power machinery, valves, water pumps, textile machinery, etc. In chemical engineering, cement prefabricated parts, plastic molding and other operations, it is used for assembling and disassembling vacuum tanks, reaction kettles, cement templates, and demolding of threaded plastic parts in the production process; It can also be used for the installation, maintenance, and replacement of cement sleepers, truss nodes, angle steel scaffolding and other structures in railway, bridge, construction and other engineering projects.

Socket wrenches have high operational accuracy and can meet the requirements of mechanical manufacturing for assembly quality. Using a socket wrench is not easy to damage the edges of the nut and can effectively protect the surface of the screw and nut, making it safer and more reliable to use.
