A method of using a fastener torque-tool body, torque arm, and release bolt to engage a stripped threaded fastener in an object. The method comprising the steps of selecting a torque-tool body suitable for the fastener being removed, engaging the torque-tool body with the fastener, engaging the torque arm with the torque-tool body, applying rotational force to the torque arm to rotate the fastener within the object, engaging the release bolt with the torque-tool body, and applying rotational force to the release bolt to dislodge the fastener from the torque-tool body.

A tool for insertion and extraction of temporary fasteners that enables by a plurality of retractable elements, an automatic engagement of the tool on the head of the temporary fastener, without the need for any rotation of the tool with regard to the head, and by lockable grasping units, operated internally locking elements, a high retention and extraction force is achieved, favouring the elimination of the risk of the clamp detaching itself from the tool, enabling control of the entire insertion and extraction process of temporary fasteners. Rapid, effective automation of the use and procedure of the temporary fasteners can be achieved, improving economic profitability and the reliability of their use.

A socket for rotatably fastening or unfastening a jackbolt of a multi jackbolt tensioner the socket extending between a first end and a second end such that the first end is adapted to receive the jackbolt, the socket comprising: a passage extending along a length of the socket to receive a head of the jackbolt, the passage being defined by a plurality of even-numbered internal side walls dimensioned to engage a plurality of sides of the head of the jackbolt received therein, the socket having a central axis with diametrically opposed pairs of said side walls being parallel to each other, and pairs of adjacent side walls meeting to form corner portions to receive corners of the jackbolt head; a plurality of guiding members arranged circumferentially about an opening of the passage to guide the head of the jackbolt into the passage and align the plurality of sides of the head of jackbolt such that corners of the jackbolt head are aligned into position with corner portions of said pairs of adjacent side walls.

Range taking shear bolts and bolt installation (drive) tools are described herein, which are configured for use with a variety of range taking connectors and conductors.

A method for connecting a screw and a rotary tool in a rotationally fixed manner, wherein the drive surfaces of the driving profiles have a constant inclination relative to their profile axis, which is the same for all drive surfaces of both components. In the component with the outer driving profile, the drive surfaces are all concave or all convex, and in the component with the inner driving profile, the drive surfaces are curved complementary to the drive surfaces of the outer driving profile, in such a way that, in the plugged-together state, the drive surfaces of the two components, viewed in the circumferential direction, come into surface contact/engagement with one another on both sides of the apex of the concave/convex curvature. The driving profiles are designed in such a way that they do not come into contact with each other in the transition regions located between the drive surfaces.

A hex headed bit and socket for enhanced non-slip application of torque force having a hex head with contoured fastener engagement surface channel within the respective first and secondary alternating flat tool engagement sides. The contoured channels are tapered transversely and extend in angular inclination across hex head bit flat side. The defined primary channel lateral edges correspondingly embed themselves during rotational engagement within the so engaged fastener pulling the hex head bit into the engaged fastener imparting enhanced translateral points of tool engagement.

A hex headed bit and socket for enhanced non-slip application of torque force having a hex head with contoured fastener engagement surface channel at the center of the respective alternating flat tool engagement sides. The contoured channels are tapered both transversely and longitudinally and extend in angular inclination across hex head bit flat side. The defined primary channel lateral edges correspondingly embed themselves during rotational engagement within the so engaged fastener pulling the hex head bit into the engaged fastener imparting enhanced translateral points of tool engagement.

Methods and apparatus for a fastener head having a dual zone socket area and a mating driver bit according to aspects of the present technology include a fastener configured with driving surfaces adapted to provide enhanced engagement between each other during use. The fastener includes a recessed socket area with a sidewall that has an upper inwardly tapering section and a lower vertical section that extends to the bottom of the recessed socket area. The upper inwardly tapering section of the sidewall may also include an offset relative to the lower vertical section to create asymmetrical driving and removal surfaces. The technology also includes a corresponding mating driver bit configured with mating surfaces to the fastener to provide enhanced engagement between the fastener and mating driver bit. The technology also allows either the fastener or the driving bit to be used with preexisting fasteners and driver bits.

A clamping socket assembly and method includes positioning a fastener body in a collet. The collet has a first end and a second end, wherein the second end receives the body. The first end includes a tool mating member. The collet has a perimeter wall having a plurality of slots extending therein that extend into the second end to define a plurality of wings. A sleeve is positioned on the collet and is threadably coupled to the collet. The sleeve is rotated in a first direction to threadably couple the sleeve to the collet such that the sleeve moves toward the second end and urges the wings into frictional engagement with the fastener body. A tool is extended through the distal end and into the tool mating member. The tool is rotated to rotate the collet and the body.
