An apparatus for removing lug nuts for changing a tire on a vehicle has a bracing structure and at least three arms connected to the bracing structure. A first arm extends upward and a second arm, adapted to operate as a footrest, extends outward and both arms are positioned such that one may stand on the second arm to generate extra torque while grasping the first arm for stability. A third arm is adapted to receive a socket and is oriented along the socket's axis of rotation. All arms are collapsible for storage.

A bidirectional extraction socket may include a driven end configured to receive drive power from a driving tool, a drive end configured to interface with a fastener, and a body portion extending between the driven end and the drive end about an axis of the extraction socket. The drive end includes a fastener engagement recess extending into the body portion and coaxial with the body portion. The fastener engagement recess is configured to engage with the fastener such that the fastener is drivable in either a clockwise or a counterclockwise direction while avoiding contact with corner portions of the fastener.

A socket-shaft connection assembly for motorsport pneumatic impact wrench includes a socket-holding shaft, a socket, a fixing element for connecting the socket to the socket-holding shaft along an axis of the socket-holding shaft, wherein: the socket-holding shaft and the socket include respective grooved profiles cooperating for the torque transmission between the socket-holding shaft and the socket; the fixing element is conformed to exert a force in the direction of the axis of the socket-holding shaft to connect the socket to the socket-holding shaft; on the fixing element, on the socket-holding shaft and on the socket a plurality of coupling conical surfaces are obtained for centering said socket on said socket-holding shaft, wherein the coupling conical surfaces are distinct from the grooved profiles.

An electrically isolated adapter may include a drive body made of first metallic material extending along a common axis, a driven body made of a second metallic material extending along the common axis, and an isolation assembly formed of insulating material disposed between the drive body and the driven body. The drive body may include a drive head configured to interface with a socket or fastener. The insulating material has a resistance to electrical current that is higher than the resistance to electrical current of at least one of the first metallic material and the second metallic material. The driven body may include a drive receiver configured to interface with a protrusion of a driving tool. A portion of one of the drive body or the driven body is received inside a portion of the other of the drive body or the driven body such that the drive body and driven body overlap each other along the common axis.

A ratchet tool comprises a base, a ratchet body, a switching member and a pawl member. The base has a rail and is movable with linear motion along the rail between a first position and a second position, the ratchet body has plural teeth, and the pawl member is engaged with the switching member and comprises plural ratchet teeth, a first abutting portion and a second abutting portion. When the switching member is movable to the first position, the pawl member is pivotally rotated to a third position to make the ratchet teeth mesh with the teeth and the first abutting portion abut against the base, therefore the ratchet body enables to rotate along a first rotation direction. When the switching member is movable to the second position, the pawl member is pivotally rotated to a fourth position to make the ratchet teeth mesh with the teeth and the second abutting portion abut against the base, therefore the ratchet body enables to rotate along a second rotation direction.

A socket driver for a perforating gun assembly. The socket driver includes a first end, and a second end opposite the first end. The second end defines an inner diameter that has a length to extend over a threaded end of the tandem sub. The socket driver is configured to mate with a shoulder along the tandem sub of the perforating gun assembly. Specifically, the socket driver includes a radial notched profile. The notched profile is configured to mate with a radial pattern of slots along the shoulder of the tandem sub. In one aspect, the socket driver is between 3 and 8 inches in length. In one aspect, the first end of the socket driver comprises an opening configured to receive a torque tool. A method of connecting ends of perforating guns using the socket driver is also provided herein.
