Anchor Rod Torque Wrench Extension Socket

The anchor rod torque wrench extension socket is used for installing nuts with pre-tightening force on anchor rods in coal mine underground. It is a commonly used tool for production, maintenance, and daily tasks. Socket wrenches consist of multiple sockets with hexagonal or dodecagonal holes, along with handles, extension rods, and other accessories, making them particularly suitable for tightening bolts or nuts in very narrow or deeply recessed spaces. The surface treatment uses phosphating: black but without gloss. The socket is immersed in a phosphating solution, forming a layer of insoluble crystalline phosphorus on the surface, which is the conversion process of phosphate. The extension socket can be used with anchor rod drilling machines, pneumatic wrenches, air impact wrenches, manual torque wrenches, and other equipment.
