Abstract: ABSTRACT A PORTABLE FASTENER DEVICE FOR EXTENDED BOLTS The present invention discloses a portable fastener device (20) for extended cylindrical threads for to reduce the tightening/loosening time of bolt/nut and to reduce the manual effort. The portable device (20) comprises a frame and a pinion. The cylindrical hollow gear is configured to receive the rotary motion from the pinion (1). The said hollow gear (2) transfers the horizontal rotation of pinion into vertical rotation of the chuck, wherein the chuck securely holds the bolt/nut for tightening/loosening purpose. The motor (5) is operatively connected with the pinion for to provide the rotary motion. The speed controller is configured to control the rotational speed of the motor for preventing the damages of nut/bolt due to excessive torque. The digital meter is configured to show the rotational speed, battery status, forwards and reverse, number of operations and the like. The twin hammer mechanism (15) is positioned with the hollow chuck for regulating the rotational pressure when the completion of tightening of bolt/nut. The said hollow chuck/gear allows the extended cylindrical threads through its inner hollow area for tightening/loosening the nuts from the various extended distances of bolt.
