- Size Guide
- A torque wrench is a tool used to apply a specific torque to a fastener such as a nut or bolt. It is usually in the form of a socket wrench with special internal mechanisms
- A torque wrench is used where the tightness of screws and bolts is crucial
- It allows the operator to set the torque applied to the fastener so it can be matched to the specifications for a particular application
- Measuring bolt tension (indirectly via bolt stretch) is actually what is desired, but often torque is the only practical measurement which can be made.
