torque-angle tightening (also known as torque-angle tension control) is a method of securing the bolted joint when the initial tension is critical for reliability and safety. The technique relies on simultaneous monitoring of both the torque applied during the tightening as well as the angle of rotation, usually using a torque/angle wrench.

The torque is then related to the lever length, shaft diameter and measured force. The device is generally used over a range of engine speeds to obtain power and torque curves for the engine, since there is a non-linear relationship between torque and engine speed for most engine types. Power output in SI units may be calculated as follows:
Four narrow-clearance hydraulic torque wrenches on a flange. A hydraulic torque wrench is a power tool designed to exert torque on a fastener to achieve proper tightening or loosening of a connection through the use of hydraulics. A torque wrench is applied to the nut either directly or in conjunction with an impact socket. Hydraulic torque ...
