Tools, for example, hexagon sockets, dodecagonal sockets, splined sockets, wrenches, etc., that have inner surface geometries adapted to engage a flank of a fastener at a point away from a corner of the fastener. This increases the strength and life of the socket, reduces a risk of the fastener becoming locked or stuck in the socket, and reduces the risk of the fastener being stripped or the socket slipping on the fastener.

Socket drive improvement

Sockets, for example, hexagon sockets, dodecagonal sockets, and splined sockets, that have inner surface geometries adapted to engage a flank of a fastener at a point away from a corner of the fastener. In general, the sockets engage the flank of the fastener at a distance of about 30 to 60 percent of half a length of the flank away from the corner of the fastener. This increases the strength and life of the socket, reduces a risk of the fastener becoming locked or stuck in the socket, and reduces the risk of the fastener being stripped or the socket slipping on the fastener.

Adjustable pliers includes a first plier half, a second plier half coupled to the first plier half, and a stud disposed in a slot of the second plier half. The first plier half includes a first handle and a first working tip opposite the first handle. The second plier half includes a second handle and second working tip opposite the second handle. The slot extends along a path from a first end of the path to a second end of the path, the path extends in a first direction at the first end of the path and extending in a second direction substantially parallel to the first direction at the second end of the path. A performance parameter is defined, at least in part, by a relationship between dimensions of the slot or of the second working tip.

A crimping tool with a crimping opening extending at an angle to the axial direction of the tool. The tool can include jaws with multiple crimping openings cooperatively defined thereby at different angles relative to the longitudinal axial direction of the tool. For example, the crimping openings can begin at a respective faces of the jaw and such faces can extend at different angles relative to the longitudinal axial direction of the tool. In this manner, the tool can allow crimping of connectors at a variety of different angles, reduce jaw length and width, and improve the leverage of the crimpers.

Disclosed is a tool, such as pliers, with handle offsets and stop features. In an embodiment, the tool has a minimum of about 0.50 inches of clearance between handles in an area where a user's index finger contacts the handles. This is accomplished by offsetting upper and lower handles of the tool. For example, the lower handle may be offset about 1.10 inches from a pivot point between the handles. Similarly, an end of the upper handle may be offset by about 1.150 inches from the pivot point when jaws of the tool are adjusted to a closed position.

Tool with handle offsets

Disclosed is a tool head, such as a socket, having an annular groove that allows gripping of the tool head to remove the tool head from a tool having a lug, such as ratchet, torque or impact wrenches. The groove is spaced from the drive engagement end of the socket for improved gripping performance. The groove dimensions were determined to improve gripping performance as well. For example, the groove can have a depth of 0.020&#x2033;-0.050&#x2033;, preferably 0.020&#x2033;-0.030&#x2033;. More broadly, the groove can have a depth of 5.0%-15.0%, and preferably 5.0%-10.5%, of the drive end outer diameter. The groove can, either alone or in combination with the above ranges, have a width of 0.25-0.47&#x2033;, preferably 0.29-0.43&#x2033;. The groove can, either alone or in combination with the above ranges, begin at a distance of 0.070-0.160&#x2033;, preferably 0.090-0.140&#x2033;, and have an end of groove farthest from the end of the socket of 0.32-0.63&#x2033;, preferably 0.38-0.57&#x2033;.

A lift arm of a floor jack is composed of a number of components made from metal bar stock. The lift arm is adapted to transfer power and motion from a power unit to a saddle, which is adapted to be placed at a lift point of the vehicle, thereby applying pressure to the lift point and raising the vehicle.

Methods and systems for increasing the efficiency of a remote wrench. The remote wrench can include a flexible plate within the tool housing or as part of the housing that is more flexible than the rigid housing in conventional remote wrenches that has been shown to limit efficiency. Additionally, a fixed support and a base can be provided that are collectively capable of being coupled to the remote wrench, preferably at the flexible plate, to increase efficiency. The remote wrench operation is therefore improved by reducing inefficiencies and providing a maximum torque output.

A hydraulic power unit for a floor jack that includes an internally-adjustable relief valve that is inaccessible to an operator without removing the power unit from the jack assembly and disassembling the power unit. By placing the relief valve inside of the hydraulic assembly, hidden from operators, the relief valve is less likely to be accidently adjusted when using or servicing the jack.

A method of manufacturing a punch, such as a socket punch, using wire EDM with at least six steps. The method involves forming a blank, holding the blank with an adapter, machining grooves in the blank, manufacturing a side relief of a working portion using wire EDM, milling the working portion to a final size, and forming a cone point on the end of the working portion. The method allows the punch to be manufactured more quickly and from a CAD model, therefore removing the need for over-specialized equipment and improving manufacturing times.

A corner reinforcement gusset with a radial or other shaped cutout at an internal corner of the gusset. The cutout can alleviate the stresses at that corner and reduce failure. The gusset can therefore better reinforce an enclosure or other object to maintain the structural stability of the object better than prior art gussets.
