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 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 method of using a fastener torque-tool body, torque arm, and release bolt to engage a stripped threaded fastener in an object. The method comprising the steps of selecting a torque-tool body suitable for the fastener being removed, engaging the torque-tool body with the fastener, engaging the torque arm with the torque-tool body, applying rotational force to the torque arm to rotate the fastener within the object, engaging the release bolt with the torque-tool body, and applying rotational force to the release bolt to dislodge the fastener from the torque-tool body.

The screw remover includes a head portion and a tail portion. The tail portion is coaxial to the head portion and is a frustum. A terminal face is formed at an end of the tail portion remote from the head portion. A diameter of the tail portion is reducing from toward the terminal face. At least one thread is formed on a peripheral face of the tail portion and spirally extends around an axis of the tail portion. At least one groove is formed on the peripheral face of the tail portion and traverses the at least one thread. An end of the at least one groove extends to the terminal face. Thereby, the screw can be rotated to remove by a driving tool when the tail portion is inserted into the screw and the head portion is connected to the driving tool.

A pliers includes a first handle and a second handle. A first jaw is fixed with respect to the first handle and includes a distal tooth, a cone portion, and a blade portion. A second jaw which is fixed with respect to the second handle includes a distal tooth, a cone portion, and a blade portion. A pivot pivotably connects the two handles such that when the pliers are shut, the two teeth are aligned, the cone portions are aligned, and the blade portions are aligned.

A fastener extractor tool and a method of using said tool. The tool comprising a torque-tool body, a plurality of engagement features, and a plurality of gripping edges. The engagement features radially positioned around a rotational axis of the torque-tool body and each comprising a first slanted section, a second slanted section, and a hollow section. The first and second slanted sections terminally and oppositely connected to the hollow section and an acute cavity angle being delineated between the first and second slanted sections of each engagement feature. The method comprising providing the fastener extractor tool, engaging the torque-tool body and engagement features with a fastener, cutting a channel into the fastener with the gripping edge, and rotating the fastener with the torque-tool body.
