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 device for the automatic manufacture of screw connections by a screw includes a motion system with which the screw can be led to the components to be connected. The screw is taken up by an automatic screwing arranged on the motion system. A protective sleeve is arranged so that it can be moved with the automatic screwing unit. The protective sleeve acts as protection, surrounds the screw, and is arranged out of contact with one of the components to be connected.

An improved open-ended wrench that is adaptable for engaging hexagonal head nuts with non-specific engagement surfaces. The wrench provides a handle with an open working end having opposed flat jaw working surfaces with a positional work piece engagement cavity there between. A contact enabling contoured notch cutout in each flat inside working surface with corresponding standard and non-standard support and torque engagement surface respectively inwardly from the junction of the concave cavity portion.

A spanner for simultaneously gripping a plurality of fasteners. The spanner includes a body, the body having a plurality of spaced apart fastener grips for simultaneously gripping the plurality of fasteners. The spanner also includes at least one attachment member for attaching the spanner to a structure the fasteners attach to.

A socket having a working end with a work piece aperture that is adapted to receive a work piece and an opposing drive end adapted to engage a torque application tool. The socket includes a biasing member adapted to apply a biased frictional force to the work piece received in the work piece aperture and including first and second opposing ends, where the first end is restricted from moving in the radial direction, and the second end includes a bent portion and is restricted from moving in the axial direction, and a groove formed in an internal surface of the work piece aperture. The bent portion engages the groove.

A tool for use with a fastener includes a drive shaft extending along a longitudinal axis from a proximal end to a distal end. The tool includes an engaging tip extending from the distal end, the engaging tip sized and shaped to detachably engage a receiving portion of the fastener, wherein the engaging tip is rotationally fixed to the fastener when the engaging tip is engaged with the fastener. The tool includes a compressible winged member extending distally from the drive shaft, the compressible winged member moveable between compressed and uncompressed positions. In the uncompressed position, the compressible winged member spans a distance greater than an internal diameter of a portion of the receiving portion.

The disclosure relates to a screwdriver attachment for screws, which has a first shaft section with a first longitudinal axis, and a second shaft section with a second longitudinal axis. The second shaft section is coupled to the first shaft section via a linking disk. The first shaft section has a free end with which the screws are turned. The first shaft section and second shaft section are connected to one another by a spring element, which aligns the first shaft section in a starting position in which the first longitudinal axis and the second longitudinal axis are aligned coaxially. Screws can be readily turned with the screwdriver attachment according to the disclosure, even if there is a certain offset between the axes.

A fastener device is disclosed. The fastener device includes a hub defining a bore, an attachment shank including a proximal stop and distal bit received within the bore, a retainer releasably engagable with a proximal end of the hub and a defining a passageway for a proximal mounting end of the attachment shank, a biasing element engaged with the proximal stop, and a split cam assembly disposed within a distal end of the bore. The split cam assembly is biased toward a closed configuration for engaging and retaining the head of a fastener, and is piovtable upon distal advancement of the attachment shank and distal bit, against the head, to release the head from engagement with the split cam assembly.

Expandable spinal implants, systems and methods are disclosed. An expandable spinal implant may include a first endplate, a second endplate, and a moving mechanism that is operably coupled to the first and second endplates. The moving mechanism may include a wedge, a first sliding frame and a second sliding frame disposed on opposite sides of the wedge, a screw guide housing a rotatable first set screw and a rotatable second set screw opposite the first set screw. The first set screw may be operably coupled to the second sliding frame and the second set screw may be operably coupled to the wedge. The moving mechanism may operably adjust a spacing between the first and second endplates upon simultaneous rotation of the first and second set screws and operably adjust an angle of inclination between the first and second endplates upon translating the first set screw or second set screw.
