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 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.

A flexible shaft includes a tubular body extending along a central longitudinal axis and having proximal and distal ends opposite one another. The flexible shaft also includes a slot defined by the tubular body and extending along a helical path around and along at least a portion of the body between the proximal and distal ends. The helical path extends around the portion of the body for a plurality of rotations. The slot defines at least two teeth adjacent one another along a direction parallel to the central axis. Each tooth of the two teeth has a feature. In some implementations, a line extending through center points of the features on the two teeth is angularly offset from the central longitudinal axis. In some implementations, a line parallel to the central longitudinal axis intersects a different point on each feature of the two teeth.

A tool extension adapted to couple to a drive lug of a driver and a tool that allows the tool to reach hard to reach places without room for a coupling. The tool extension voids the need for a larger diameter coupling by including a female recess in an end of the tool extension that receives the bit into the shaft itself.

A screw element is disclosed having a shaft with an outside screw thread and a longitudinal axis extending along the shaft and thereby defining a distal direction and a proximal direction, and an insertion direction and an opposite removal direction, and has a tool attachment point starting radially inwards and the tool attachment point has a central opening and in the wall of this opening at least five tooth profiles directed radially outwards and mainly parallel to the screw axis directed radially outwards and mainly parallel to the screw axis are formed in the wall of this opening, and for each tooth profile an insertion wall in insertion direction and a removal wall in removal direction can be separated, characterized in that the surface of the insertion wall is greater than the surface of the removal wall.

The present patent of privilege of invention belongs to the field of general purpose tools, and is more specifically a universal screwdriver, notably, it adapts to the most varied models of screws, allowing the user to use the same tool to screw or loosen the screws, saving the cost of obtaining different keys and also saving the space for storing the tools.

A tool is provided in order to facilitate utilization by users in a wide variety of applications. By way of example, a multipurpose tool includes a first handle having a first axle and a second handle having a second axle; a first jaw and a second jaw, defining a stowed position and a deployed position, where in the stowed position the first jaw is received within the second handle and the second jaw is received within the first handle; a third jaw and a fourth jaw, defining a stowed position and a deployed position, where in the stowed position the third jaw is received within the second handle and the fourth jaw is received within the first handle, where the first jaw and fourth jaw are pivotably attached at the second axle, the second jaw and third jaw are pivotably attached at the first axle.

A screwdriver comprises a handle including a butt and a shank extending from the handle and including a tip. The butt includes a first indicating element having a shape corresponding to the tip and a plurality of second indicating elements arranged around the first indicating element. Each of the second indicating elements has the shape.

A lockable tool with a sliding scale release is formed with a frame and a tool coupled to the frame with a locking mechanism to lock the tool into an extended or retracted configuration. A release mechanism is attached a scale on the side of the frame. The scale is coupled to the frame. The tool is constructed such that sliding the scale along a longitudinal axis of the frame automatically unlocks the tool from the extended or retracted configurations. The tool can open and/or close automatically. The tool, such as a knife, can swing open or extend out a front opening in the frame.

A hex headed bit and socket for enhanced non-slip application of torque force having a hex head with contoured fastener engagement surface channel within the respective first and secondary alternating flat tool engagement sides. The contoured channels are tapered transversely and extend in angular inclination across hex head bit flat side. The defined primary channel lateral edges correspondingly embed themselves during rotational engagement within the so engaged fastener pulling the hex head bit into the engaged fastener imparting enhanced translateral points of tool engagement.
