Socket wrench conforming to DIN 896 B standards, made of hardened steel and matte finish for high durability. Widely used for tightening or loosening both screws and nuts, the wrench is designed with a fully hollow double hex socket to provide a firm grip on nuts and bolts in recesses or deep locations. In addition, this hollow design makes the tool lighter without compromising strength. It features cross holes in the body for insertion of a rotating rod to act as a lever, providing greater tightening capacity in demanding applications. The socket wrench is available in different sizes: from 6-7 to 30-32.
