An example torque wrench is provided. The example torque wrench may include a drive head configured to engage with a tool for rotating a fastener. The drive head may have a drive axis about which the drive head rotates when rotating the fastener. The torque wrench may also include a deflection member coupled to the drive head and an outer body coupled to the deflection member at a first loading point and a second loading point. The torque wrench may also include a first strain gauge coupled to the deflection member between the drive head and the first loading point, and a second strain gauge coupled to the deflection member between the first loading point and the second loading point.

A ratchet wrench assembly is provided that includes a head, a ratchet gear, a yoke, one or more drive pins, a body, and a ratchet pawl. The body may include one or more drive edges and a fastener drive member. A first drive edge may be engaged with a first drive pin such that reciprocation of the yoke causes rotation of the body and the fastener drive member about the axis of rotation via engagement of the first drive pin between the inner surface of the yoke ring and the first drive edge. The ratchet pawl may include a first ratchet tooth configured ratchet against gear teeth of the ratchet gear to permit movement of the body relative to the head in a first rotational direction and engage the gear teeth to prevent movement of the body relative to the head in second, opposite rotational direction.

Bolt extractor

A threaded fastener extractor (or) includes a drive end configured to interface with a powered driver where the drive end has a shaft, and an engagement end coupled to the drive end coaxial with the drive end about an axis. The engagement end is configured to engage with an extraction hole () formed in a threaded fastener (). The engagement end includes side cutting edges (or) disposed on lateral sides of the engagement end and end cutting edges (or) disposed at a distal end of the engagement end. The side cutting edges (or) and the end cutting edges (or) each provides engagement areas for torque transfer between the extractor (or) and the threaded fastener ().

A torque wrench () may include a body (), a force detector () operably coupled to the body and configured to detect a bending force applied to the body, and a user interface () operably coupled to the body and the force detector. The user interface may be configured to include a setting mode in which a variable feature of the torque wrench is adjustable. The user interface may be further configured to, when in the setting mode, adjust the variable feature based on the bending force applied to the body and detected by the force detector.
