Disclosed are aspects of exemplars of torque-limiting devices, methods and mechanisms. Exemplary methods may include placing an actuator in a tool containment interface of a handle, the interface being fluidly connected to an adjustment interface and adjustable via a fixation fastener; movably mounting a tool portion with an actuation catch and a work piece engaging region (WER) in the interface; applying sufficient force to the movable mounting to the handle may be via pins, guides and slots. Said catch may be one of a body catch and a lever catch; and, the actuator terminates on one of a ball shaped end that forms an interface with the body catch and a force lever that forms an interface with the lever catch.

A torque structure includes a first body, a second body, a first elastic member, a third body, and a limit unit. The second body is provided with a second receiving chamber, a first pivot portion, at least one first positioning portion and at least one second positioning portion. The first elastic member is received in the second receiving chamber. The third body is provided with a drive portion, a pivot seat, a second pivot portion, and a first limit portion. The limit unit is assembled with the second body and the third body and rotated between a disengaging position where the third body is unlocked from the second body and has a torque slip function relative to the second body, and a engaging position where the third body is locked by the second body and does not have a torque slip function.

Apparatus and method are disclosed for engaging a guide pin for installation or removal. The tool has a housing with a plunger positioned within the housing. A support tube has at least two extensions that protrude from the housing when an engagement mechanism is depressed and grips the guide pin when the engagement mechanism is released.

A quick-turning wrench includes a driving end with a first jaw and a second jaw. The first and the second jaws respectively have a first and a second side, which face one another. The driving end defines an engaging space between the first and the second jaws. The driving end has a first grip-surface section, a second grip-surface section, and a third grip-surface section. The engaging space is partially delimited by the first, the second, and the third grip-surface sections. The first grip-surface section is adjacent to the first side and extends along a flat first phantom surface. The second and the third grip-surface sections are adjacent to the second side and respectively extend on a flat second phantom surface and a flat third phantom surface.

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.

The present disclosure provides a tool comprising a centrally placed tool head disposed between first and second handle portions which a user may grip with either hand in order to comfortable apply torque about the central toolhead from either side in a safe manner. The ability to effectively utilize force from both arms without losing balance facilitates a greater application of torque. The tool may be a wrench of any type utilizing a central wrench head of any type, but may also be another type of leverage-based tool such as a screwdriver or hammered tool.
