The present invention discloses a ratchet wrench consisting of socket head at one end, an extended arm in the middle and a pivoting extension arm having an extended handle grip at the opposite end. The socket wrench is designed in a manner to install and tighten nuts onto machine bolts and break loose and remove nuts wherein the nuts are in a confined or recessed area making it difficult to reach with conventional ratchet wrench extension mechanisms.

A driving apparatus is used for simultaneously tensioning the jackbolts of a multi-jackbolt tensioner and includes a central drive gear mounted for rotation along a central drive gear axis. An annular array of spindles surrounds the central drive gear, each spindle independently mounted for rotation, with one spindle associated with one of the jackbolts. A socket on one spindle end is configured to receive one of the jackbolts. A spindle gear surrounds each spindle and is configured to rotate the spindle. The spindle gear is meshed with the central drive gear to be rotated by the central drive gear, wherein at least one spindle gear is offset along the central drive gear axis from at least another spindle gear. A slip clutch is positioned radially between each spindle gear and the associated spindle, wherein rotation of the jackbolts is up to a torque setting of the slip clutch during tensioning.

The present invention is an improved offset torque drive assembly and system capable having application of accurately torqueing a fastener in an opening offset from a channel or other fasteners in inaccessible locations. The offset torque drive assembly and system comprises a housing formed in upper and lower enclosure portions that encompasses an input gear and an output gear there-between. The input gear has a tool adapter portion configured to receive the drive shaft of the drive means so as to rotate the input gear. The output gear has a socket fastener aperture configured to receive and move the fastener by application of torque forces upon the input gear operably connected to the output gear. The output gear may be provide with a socket adapter portion configured as a cupped-socket portion to efficiently and effectively torque a fastener along lengths of an elongated threaded rod. The offset torque drive system includes the offset torque drive assembly with a spline drive and a spline insert. The spline insert is configured with a socket fastener aperture that may be formed in numerous designs and sold as a kit in order to provide the user with multiple options of socket shape to cooperate with the fastener, for example, square, Philips-head, hexagon, star, and other fastener shapes. Consequently, the offset torque drive system has an output gear with splines to receive a spline insert functioning to provide the user with the ability to connect to numerous variations of fastener heads and shapes allowing the offset torque drive to accurately torque to a fastener in an opening offset from a channel, fasteners in inaccessible locations, and a fastener in difficult confined areas as well as to easily change to a cupped-bottom fastener aperture configured to efficiently and effectively torque a fastener along lengths of an elongated threaded rod.

A crimp tool includes a frame, a lead screw and a nut assembly connected to the lead screw. A spring member is connected to the frame and movable with rotation of the lead screw. A first transducer is connected to the nut assembly to measure a first force applied on the nut assembly. A second transducer is connected to the spring member to measure a second force applied thereon by the spring member.
