A mechanism for reducing time-lost to tedious but necessary adjustments while using a chainsaw is disclosed, as well as methods of manufacture and use. An embodiment has a metal part fitting inside a plastic handle portion, where the two are sometimes assembled in two halves and then pressed molded or fastened together, in the form of a pull-handle positioned at the end of a starter-cord on a chainsaw. Another embodiment has the metal part containing a flat-blade screwdriver surface at one end, which matches and mates with some type of slotted adjustment fixture within the chainsaw; and where the other end has a socket wrench which matches up with an adjustment bolt within the chainsaw. Yet another embodiment has a dog-bone (socket) wrench fitting at one end, and a flat-blade at the other end.

A headrest support includes a head portion, a body portion, and a through hole formed inside. An elastically deformable projection is formed to extend from a lower edge of an opening provided in an outer peripheral surface of the body portion. The headrest support is inserted into a holder and supported while the projection is engaged in a locking hole. The removal tool includes a shaft portion and a handle portion. A vertical wall portion is formed at a leading end of the shaft portion, wherein the vertical wall portion is configured to enter into a side gap between a peripheral edge of the opening and the projection when the shaft portion is inserted into the through hole, and wherein the vertical wall portion is configured to be able to deform the projection toward an inside of the through hole when the shaft portion is rotated.

A torque socket having torque value indication, includes: a main body, one side thereof axially disposed with an insertion part and another side thereof axially formed with an accommodation slot, wherein at least one guiding tenon and an indication ring are radially and axially disposed on an outer circumference of the accommodation slot respectively, an outer circumference of the indication ring is annularly provided with torque value marks; a torque adjusting assembly, including a spring and a shaft cylinder, wherein an outer circumference of shaft cylinder is radially formed with an arc-shaped guiding slot allowing the guiding tenon to be inserted, the shaft cylinder can axially compress the spring for adjusting a torque value; and an end cover ring, having an indication mark at an outer circumference thereof. Accordingly, the indication mark can be aimed at one of the torque value marks for displaying a locking torque value.

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.

The present invention is a device, system and method for removing stuck brake key screws. Specifically, the invention is capable of ensuring a more effective means and method for removing stuck brake key screws from an aircraft's landing gear wheel hub half. More specifically, the invention provides for optimal or virtually optimal engagement of the device with the head of a screw to be removed, and which, it is the inventor's belief, allows for the virtually optimal transmission of screw removal torque to a screw, which should minimize the likelihood of stripping the head of the stuck screw and, if stripped, the need to expend the time and effort to drill out the screw.

A twist-drivable pin assembly includes first and second drivers, each having a driving end which can be received in a bore in the end of a twist-drivable pin, and an opposite end at which torque can be applied. The cross-sectional shape of each of the drivers at its driving end has a first plurality of apexes whose relative locations coincide with the apexes of a regular polygon such as a hexagon. The drivers differ from one another in their cross-sectional shapes at the driving end by virtue of one or more faces of at least one of the drivers between adjacent pairs of apexes having a groove formed in it. Each of first and second twist-drivable pins has a bore extending into it which is defined by a second plurality of apexes arranged as a regular polygon such as a hexagon and which is open at one end.

An optical axis adjustment device that adjusts an optical axis of a headlamp includes an aiming screw that is provided extending from inside to outside the headlamp and that has an operation portion outside the headlamp, and an aiming guide. The aiming guide is disposed outside the headlamp and includes: a cover portion that covers the operation portion of the aiming screw; a guide portion that has a tool insertion space inside and that is provided extending linearly from the cover portion; and a locking cap portion that is provided on an end portion of the guide portion away from the cover portion and that is configured to cover an opening of the tool insertion space.

A camera mounting system includes a mount and a mounting bracket removably coupled to the mount. The mount includes a plate and a screw extending rearward of the plate. The mounting bracket includes a tab and a base pivotably coupled to the tab. A camera may be mounted to the mounting bracket. In addition, a tool having a bit and configured to to interfit with a head of the screw to secure may be used to secure the mount to a tree-like object. The tool is further configured to interfit with an orifice formed in the mounting bracket and allow a user to lift the mounting bracket and removably couple the mounting bracket to the mount.

A fastener system includes a fastener including a fastener first end and a longitudinally opposed fastener second end, and an anchor configured to receive and capture the fastener upon rotation of the fastener in a first direction, wherein the anchor is further configured to engage the fastener first end upon complete rotation of the fastener in the first direction, and the anchor is further configured to prohibit further rotation in a second direction, opposite the first direction, upon engagement with the fastener first end.
