Draper torque wrench

A torque wrench is a tool that is used to indicate and precisely set the amount of force being applied to a fastener such as a nut or bolt. A torque wrench usually takes the form of a socket wrench with a special internal mechanism. The type most commonly used for automotive jobs is the clink wrench.

A torque wrench is used where the precise tightness of screws and bolts is crucial. The specs for a particular fastener can be obtainer from the manufacturer's service manual. On a click-type torque wrench, the specified torque is set on the wrench handle and the proper size socket snapped onto the wrench drive. When tightening a series of fasteners, such as the nuts on a wheel, the recommended sequence and gradation of tightenings should be followed until the specified torque is achieved on all the fasteners.
