A fastener extractor device for removing seized fasteners and aiding in disengaging the extractor device from said seized fastener afterwards. The extractor device includes a shank body, a drive head, a torque-tool body, a tubular sleeve, an external thread, and an internal thread. The torque-tool body includes a plurality of laterally-bracing sidewalls and an at least one engagement feature. The engagement feature is integrated into a specific sidewall to bite into a sized fastener. The drive head is terminally and concentrically connected to the shank body to receive an external torque tool. The torque-tool body is terminally and concentrically connected to the shank body, opposite the drive head. The tubular sleeve is slidably engaged along the shank body through the internal thread and the external thread to physically disengaged the torque-tool body from a seized fastener.

A bone screw removal device includes a shaft extending longitudinally from a proximal end to a distal removal tip. The removal tip includes a first portion at a distal-most end of the removal tip, a second portion extending proximally from the first portion and a third portion extending proximally from the second portion. The first portion is sized and shaped to be received within a retaining recess of a bone screw to clear away tissue growth as the first portion is inserted through a driving recess of a bone screw and into the retaining recess. The second portion is configured to be received within a driving recess. The third portion is configured to clear away tissue growth over a proximal end of the bone screw as the first and second portions are inserted into the retaining recess and the driving recess, respectively.

A tool for manipulating flexible and non-flexible fastening devices. The tool assembly has a flexible rod for insertion into the distal end of the fastening device. A handle assembly interacts with proximal end of the flexible rod and the proximal end of the fastening device to control of the fastening device by initiating rotation at the distal end of the fastening device.

A fastener extractor device for removing fasteners and disengaging the extractor from the so engaged fastener. The extractor includes a threaded main body with a hex drive head end portion and oppositely disposed elongated tool engagement hex body with multiple bracing sidewalls with independent contoured fastener engagement channels for fastener insertion and continued rotational removal. A tubular hex surface extractor nut is threadably disposed on the main body member for reversed thread rotation advancement to physically disengage the tool engagement body from the removed fastener.

A fastener extractor and dislodging tool apparatus includes a torque-tool body, a threaded opening, a plurality of engagement features, and a release bolt. The plurality of engagement features that grips the lateral surface of the stripped fastener is radially positioned around a rotation axis of the torque-tool body. The plurality of engagement features being perimetrically connected around a base of the torque-tool body thus delineating a socket body that removes the stripped fastener. The threaded opening traverses through the base so that the release bolt can be threadedly engaged with the threaded opening, opposite of the plurality of engagement features. When the stripped fastener is jammed within the plurality of engagement features, the release bolt can be threadedly moved into the space between the plurality of engagement features thus dislodging the stripped fastener from the torque-tool body.

An example tool is provided that includes an outer housing and an inner housing. The inner housing includes a magnetic element and is structured to travel at least partially within the outer housing under bias of a biasing mechanism. In addition, the inner housing can travel from a retracted position to an extended position. In the extended position, the magnetic element abuts or at least partially occupies a void defined by the outer tip.

Methods and apparatus to remove frangible fastener remnants are disclosed. A disclosed example apparatus to install a frangible fastener includes a drive tool having a drive socket operable to rotate a separable nut portion of the frangible fastener, and a fastener interface defining an interior for receiving at least the nut portion, the fastener interface being disposed on a drive end of the drive tool, where the drive socket is movable within the fastener interface and operable to rotate the frangible fastener, and where the separable nut portion of the frangible fastener is removed when the frangible fastener is installed. The apparatus also includes a nut-portion removal tube depending from the interior of the fastener interface, and a vacuum generator in fluid communication with the removal tube and configured to cause the separable nut portion to be removed from the interior and through the removal tube.

The invention involves the extraction process of a glow plug pencil (23) or a broken pencil (23) which is stuck in a cylinder head (13) housing (11) of a glow plug engine comprising a lower (19) and upper (17) part, so that the upper part (17) forms a shoulder (21) with the lower part (19), the pencil (23) being stuck in the lower part (19). The process is remarkable in that it includes a step (a) for drilling a bore in the pencil (23) according to the longitudinal direction of the latter which is performed with the use of a drill bit (1) comprising a drilling part (5) with flutes (7) and a shank (3) respectively having a diameter smaller and greater than the lower part diameter (19) of the housing (11) so that the shank (3) forms a shoulder (9) with the drilling part (5), and in that step a) for drilling the bore includes the drilling of the pencil (23) until the said shoulder (9) of the drill bit (1) is positioned to a stop against the shoulder (21) of the housing (11).
