| 20080257115 | BOLT-FASTENING APPARATUS AND METHOD - An apparatus for fastening a washered bolt with a flat washer passed therethrough, to a fastening object. Air discharged from an air blow nozzle is blown into a space between a head of the bolt accommodated in a socket and the flat washer. Foreign matter will be prevented from adhering to the flat washer and the bolt head. | 10-23-2008 |
| 20100095810 | HOLD AND DRIVE DEVICE - Disclosed herein is a socket driving device, comprising a drive head portion and a hand-grippable drive body portion operatively coupled with the drive head portion, the drive head portion including a socket portion for driving a target nut, the drive head portion having a pair of opposed surfaces adjacent the socket portion, the socket portion including a central fastener-receiving passage therein with a central socket axis, the central fastener-receiving passage being exposed through both opposed surfaces, a key portion for engaging a target bolt on which the target nut is to be driven by the socket portion, a key support assembly for positioning the key portion in an operative position relative to the socket portion, the key support assembly including a support frame secured to the drive body portion and/or the drive head portion, the support frame including a support arm portion extending along the drive head portion, the support arm having a free end region, the key portion being held relative to the free end region and in the operative position relative to the socket axis, the key portion being biased toward the socket portion. | 04-22-2010 |
| 20110132148 | NUT SCREWING DEVICE - A nut screwing device for screwing a nut onto a rivet which is provided on the end opposite the rivet head with a blind hole having a contour that is not round in cross-section, comprising at least one drive which is drivingly connected via a transmission to a screw-in tool that has an accommodating opening for inserting the nut, characterized in that the nut screwing device comprises an anti-rotation means having a chamber in which an anti-rotation element (bit) is movably arranged that has a head section, which substantially fills the cross-section of the chamber, a shaft section, and an adjoining end section with a contour identical with that of the blind hole, the chamber being arranged adjacent the screw-in tool and comprising a central exit opening for the shaft with the end section of the anti-rotation element and being provided on the edge of the exit opening with a surrounding shoulder as a stop for the head section of the anti-rotation element (bit). | 06-09-2011 |
| 20110146456 | STUD MOUNTING MACHINE AND METHOD OF USING SAME - A holding device for holding a stud, which includes a radially projecting flange in a securing position, comprises a collet component including a hollow tubular insertion section defining an insertion axis, and a clamping section operable to exert a radially inwardly directed clamping force for clamping the stud. A securing device is arranged on the insertion section and includes a securing sleeve formed of plurality of separate securing-sleeve sections that are radially movable relative to one another. A clearance space is defined between a bottom end of the securing-sleeve sections and a top end of the clamping section, and the clearance space is operable for holding a flange of a stud in the securing position. | 06-23-2011 |
| 20110265610 | FASTENING TOOL - This fastening tool supports a key wrench such that it cannot rotate at a location where a hexagonal hole on the tip end part comes in contact with a nut, so that even though the key wrench is pressed backward as a pin is screwed into the nut, a key wrench holder remains in a state of contact with the nut. After the pin has been screwed into the nut, the nut is twisted off at a weak section. The further the pin is screwed into the nut, the key wrench holder supports the key wrench at a location closer to the pin, which keeps the amount of torsional deformation of the tip end part of the wrench small, and thus makes it possible to securely engage with the pin, and in the final state of the fastening work, it is possible to completely twist off the twist-off type nut, which requires a large torque. | 11-03-2011 |
| 20120279361 | TIRE PRESSURE GAUGE AND FASTENING AND UNFASTENING TOOL OF THE SAME - A tire pressure gauge includes a holder, an air intake seat, and a detection device coupled with the air intake seat. The holder and air intake seat have respectively a first positioning ring and a second positioning ring. A fastening and unfastening tool of the tire pressure gauge includes an outer barrel and an inner barrel held in the outer barrel. The outer barrel has a first anchor portion to latch the first positioning ring. The inner barrel has a second anchor portion to latch the second positioning ring. The outer barrel and inner barrel respectively drive the holder and air intake seat to be fastened to an air nozzle of a vehicle tire, and the holder and air intake seat are butted tightly to allow the tire pressure gauge to be securely installed on the air nozzle of any type of vehicles through the fastening and unfastening tool. | 11-08-2012 |
| 20130091992 | PREHENSILE ANTI-TORQUE AND SIMULTANEOUS SUPPORT FOR POWER TOOL - A tool for assembling parts to be connected to each other includes, a body for rotating a first end and a second end of a bolt, and a holder attaching to the body for holding a fastener against rotation and in alignment with the second end of the bolt. The fastener does not rotate while rotatably receiving the second end of the bolt. | 04-18-2013 |
| 20130319180 | FAMILY OF TEMPORARY FASTENERS AND A DEVICE FOR INSTALLING THEM - The invention concerns a family of insertable temporary fasteners ( | 12-05-2013 |
| 20160101506 | Securing System for Power Wrenches and a Power Wrench - A securing system for power wrenches, for immobilizing a power wrench, which is placed on a threaded bolt with a nut, in an axial direction of the threaded bolt is provided. The securing system includes a securing device. The securing device includes a locking element which engages with a threaded section of the threaded bolt projecting over the nut, the locking element being movable in a radial direction relative to the threaded bolt to engage with the threaded section of the threaded bolt. | 04-14-2016 |
| 20160129567 | DEVICE FOR APPLYING TEMPORARY FASTENERS - The invention relates to a tool ( | 05-12-2016 |
| 081056000 | Gear-operated | 1 |
| 20130180364 | Fastener Installation Tool With Quick Change Key - An improved fastener installation tool is provided that is used to install a threaded nut onto a threaded fastener bolt where access to the bolt head is not possible. The fastener bolt has a threaded shank with a noncircular recess that is adapted to receive a complimentary shaped hex key or hold bit installed in a socket gear of a power driven tool which is used to install a threaded nut onto the threaded shank of the fastener bolt. A spring biased retainer slide with an extended rod portion hold the hex key securely in a locked position. Manual retraction of the retainer slide allows the extended rod portion to release the hex key so it may be replaced when damaged without any need for any further disassembly or need for additional disassembly tools. | 07-18-2013 |
