The present invention is concerned with a socket wrench comprising a socket element which is provided with a socket for engagement with a bolt or nut, and a handle which forms a lever arm when tightening or loosening nuts or bolts, which handle is fitted at a first end thereof with a hinge half for the purpose of acting in combination with a socket element fitted with a hinge half on an upper part thereof. The invention is further concerned with a second socket element hinged to a second end of the handle, or other nut wrench or similar attached to a second end of the handle.
Socket wrenches are used for tightening or loosening bolts or nuts in threaded joints that are inaccessible by non-hinged tools. Socket wrenches available on the market have a socket for engagement with the bolt or nut. The socket is located in a socket element with the hinge located above the socket of the socket element, which is fitted with a handle attached to the hinge, which handle forms a lever when tightening or loosening bolts or nuts in a threaded joint.
The drawback of socket wrenches is the location of the hinge at the top of the socket element, which restricts the ability to tighten or loosen nuts on bolts having a thread length greater than the depth of the socket of the socket element.
