Apparatuses and methods for facilitating fastening of a fastener are provided. In one example, the apparatus includes a body portion that extends distally from a body proximal portion to a body distal portion. A head portion extends distally from the body distal portion. A first prong that extends distally from a first prong proximal section that has a first thickness to a first prong distal section that has a second thickness that is less than the first thickness. A second prong that extends distally from a second prong proximal section that has a third thickness to a second prong distal section that has a fourth thickness that is less than the third thickness. The second prong is spaced apart from the first prong to define a gap therebetween that is configured to receive the fastener.

A wrench assembly, and methods of making and using such a wrench assembly, whereby the wrench assembly includes a head, an opening disposed within the head, a first pivotal member coupled to the head, a plurality of radial slots inwardly extending into the first pivotal member, and a handle, whereby the head pivotally couples to the handle.

A tool adapted to be driven rapidly includes a driving portion which has a first jaw and a second jaw and an opening between the first and the second jaws configured to receive an object to be driven. The first and the second jaws have first and second engaging sides configured to grip the object to be driven. The opening has a closed end, an open end, and two opposite sides respectively delimited by the first and the second engaging sides. The first engaging side extends along a linear line. The second engaging side extends along a curved line. The closed end of the opening has a smaller width than the open end of the opening.

A wrench includes a first part and a second part which is overlapped on the first part and is pivotable relative to the first part. The first part has a first clamping space and the second part has a second clamping space which is located corresponding to the first clamping space. The first clamping space is defined by two first jaws. The second clamping space is defined by two second jaws. When an object is clamped by the first and second parts, the second part is able to be pivoted an angle relative to the first part to allow the object to be firmly clamped by the first and second parts.

A screwing tool, including an elongate handle which, at each of the two ends thereof, bears a head pivotable about a pivot axis and having two torque transmission flanks in each case and has a force application flank for introducing a force in order to produce a torque on the head remote from the relevant force application flank, wherein, in a pivoting end position of the head, in which a stop of the head lies against a counter stop of the handle, a narrow side of the head functionally directed away from the stop forms an extension of the force application flank. The second head forms an extension of the force application flank and can be used as a hand grip.

An asymmetrical structure for an open-end wrench is disclosed. The force-applying surface of the wrench facing the opening is mainly set as an arc surface, and the force-receiving surface of the wrench facing the opening is set as a flat surface. When a nut is engaged in the opening of the wrench, one side of the nut abuts against the force-receiving surface, and the other side is in contact with the force-applying point on the arc surface of the force-applying surface. When the wrench is turned, the force of the torque can only be transmitted through the force point contacting the nut, thereby preventing the force of the torque from being dispersed.
