Abstract

A ratchet wrench consisting of a socket driver head pivoting or fixed at one end, an elongated handle in the middle, and a pivoting extension shaft having an extended handle grip at the opposite end. The wrench is designed to install and tighten nuts onto machine bolts and break loose and remove nuts from machine bolts wherein the nut is in a recessed or confined area making it hard to reach with a conventional fixed-handle ratchet wrench. The extended handle grip is generally U-shaped with a linear section perpendicular to and substantially centered about the end of the extension shaft. The U-shaped handle of the extension shaft extends the user's reach when applying the torque necessary to install or remove a nut located in a cramped work space. In addition, the U-shaped handle includes a magnet for retrieving articles that are out of the reach of the user.
