An open-end hexagonal wrench having opposing jaws extending forwardly from a handle, the respective jaws having forwardly disposed, opposing planar faces, the forwardly disposed planar faces respectively merging with outwardly curved diverging surfaces with protrusions for penetrating the side of a hexagonal fastener being turned without engaging a corner of the fastener. The rearward ends of the outwardly curved diverging surfaces respectively merging with rear, concave arcuate corners which in turn merge with gentle curves into a concave throat.

An anti-slip torque tool with integrated engagement features includes a torque-tool body and a plurality of engagement features. The plurality of engagement features is radially distributed around a rotational axis of the torque-tool body. Each of the plurality of engagement features includes a first cavity surface, a first bracing surface, a second bracing surface, and a second cavity surface. The first bracing surface and the second bracing surface are adjacently connected to each other through an intersection point. The first cavity surface is terminally connected to the first bracing surface through a first connection point as the first bracing surface is positioned in between the second bracing surface and the first cavity surface. The second cavity surface is terminally connected to the second bracing surface through a second connection point as the second bracing surface is positioned in between the first bracing surface and the second cavity surface.

A multipurpose tool that includes a handle and a body. The body has an opening that extends through the body and has a first set of pins that are removably connected to the body. The first set of pins are arranged along and adjacent to at least a portion of the perimeter of the opening and project away from the first side of the body. The multipurpose tool also includes a modular hammer and other tool features, some of which are configured to operate on a firearm for its disassembly and reassembly.

A hand tool includes a handle, at least one driving head, at least one groove and at least one abutting element. The at least one driving head is connected with at least one end of the handle. The at least one groove is disposed on an inner edge of the at least one driving head, and includes an inner wall and at least one margin structure. The at least one margin structure extends from an end of the inner wall, and an angle is between the at least one margin structure and the inner wall. The at least one abutting element is disposed on the at least one groove.

The present invention surrounds to a ratchet apparatus, system and use thereof. The invention is presented to provide additional mechanical advantage and added angular engagement of a ratcheting wrench. In particular the present invention provides increased torque and angular engagement within a compact space without requiring an extended handle, wherein an extended handle reduces portability and further restricts access and movement within confined spaces.

A wrench and nut combination, including: a wrench lug including: a wrench lug feature that substantially mates with a nut feature of a nut of a shock absorber during a first rotation of said nut, relative to external body threads on a body of the shock absorber, in a first direction, wherein the wrench lug feature and the nut feature release during a second rotation of said nut, relative to the external body threads, in a second direction, wherein at least one of the first rotation and the second rotation causes an adjustment to a compressive coil spring pre-load of a set of coil springs disposed in the shock absorber.
