A grip device for hexagonal wrenches includes a body, a rotary member, a resilient member and a fastening member. The body includes an engaging portion which includes multiple recesses, multiple first slots and an axle. The rotary member is rotatably and movably mounted to the axle. The rotary member includes a first room defined in the inner periphery of the passage through which the axle extends. A first shoulder is formed between the first room and the passage. The resilient member is mounted to the axle and the fastening member is connected to the axle. An L-shaped tool has the first section thereof received in one of the recesses and the first slot of the recess. When the rotary member is moved toward the engaging portion, the first section is inserted into the first slot. The L-shaped tool is restricted by the rotary member and used as a T-bar tool.

A nut driver includes an elongate drive shank and a reversible socket. The socket has a first hex socket opening sized to engage a hexagonal profile of a first size, and a second hex socket opening sized to engage a hexagonal profile of a second size that is larger than the first size. The socket is mountable on the drive shank in either a first orientation that presents the first hex socket opening for use, or a second orientation that presents the second hex socket opening for use. Additionally, in the first orientation, the socket is mountable in either a screw head receiving position or a drive bit receiving position.

A driving tool includes a body portion, a driving portion, and a neck portion. The driving portion defines a reference rotating axis. A distal end of the driving portion opposite to the body portion is provided with a front driving face having a first width in a radial direction of the reference rotating axis. The neck portion is disposed between the body portion and the driving portion and has a second width in the radial direction of the reference rotating axis. The second width is less than the first width.

A driving tool includes a body portion, a driving portion, and a neck portion, wherein the driving portion defines a reference rotating axis, wherein distal end of the driving portion opposite to the body portion is provided with a front driving face having a first width in a radial direction of the reference rotating axis, wherein the neck portion is formed between the body portion and the driving portion and has a second width in the radial direction of the reference rotating axis, wherein the second width is less than the first width.

A screw bit body which allows for efficient torque force application onto a socket fastener. The screw bit body includes a plurality of laterally-bracing sidewalls, a first base, and a second base. The laterally-bracing sidewalls are radially distributed about a rotation axis of the screw bit body with each further including a first lateral edge, a second lateral edge, a bracing surface, and an engagement cavity. The engagement cavity creates a gripping point to prevent slippage in between the screw bit body and the socket fastener. The engagement cavity traverses normal and into the concave surface and the convex surface. The engagement cavity includes an angled driving portion and a concave portion. The angled driving portion is positioned adjacent to the first lateral edge with the concave portion being positioned opposite to the first lateral edge, across the angled driving portion.

A driver tool for insertion and removal of a first part configured for threaded engagement in a corresponding threaded bore in a second part has a driving end portion of polygonal shape with multiple flats configured for engagement in a recess in the first part having a corresponding polygonal shape. Some or all of the flats have a respective grabbing feature or edge designed to grab or grip into the opposing surface of the recess to allow a greater amount of torque to be applied to the first part when the tool is rotated in the unthreading direction than when it is rotated in the opposite threading or insertion direction.

A wallet includes a first shell with one or more openings on a shell perimeter adapted to clip one or more objects to the one or more openings; and a second shell coupled to the first shell, the second shell including a storage compartment; and first and second rails on each side of the second metal shell to slideably receive one or more cards in the storage compartment.

Range taking shear bolts and bolt installation (drive) tools are described herein, which are configured for use with a variety of range taking connectors and conductors.

A golf club wrench with a bit portion having a plurality of tip features at one end of the bit portion is disclosed herein. The tip features may include threading, a Philips head shape, a flat head shape, a Torx® head shape, and a hex wrench shape. The different tip features on the wrench can be used to engage with both a mechanical fastener and a weight. The wrench may also include a handle contoured to fit within the hand of a golfer. The golf club wrench can be provided in a kit containing weights and mechanical fasteners having engagement features that mate with one or more of the tip features on the wrench.

A method for connecting a screw and a rotary tool in a rotationally fixed manner, wherein the drive surfaces of the driving profiles have a constant inclination relative to their profile axis, which is the same for all drive surfaces of both components. In the component with the outer driving profile, the drive surfaces are all concave or all convex, and in the component with the inner driving profile, the drive surfaces are curved complementary to the drive surfaces of the outer driving profile, in such a way that, in the plugged-together state, the drive surfaces of the two components, viewed in the circumferential direction, come into surface contact/engagement with one another on both sides of the apex of the concave/convex curvature. The driving profiles are designed in such a way that they do not come into contact with each other in the transition regions located between the drive surfaces.
