Torque wrenches can be used with specialist sockets in all kinds of tightening and fastening applications. They are essential when more professional and precise handling is necessary over a conventional wrench. This is particularly useful where uniformity is a concern, such as in production.

Tool care

Torque wrenches are precise measuring devices that require care in handling. Always place the tool in the storage box after use. Do not use cheater bars, hammers, or any other damaging object.

Calibrating your torque wrench

Torque wrenches should be calibrated to the desired level of torque with a torque analyser before use. It is recommended that micrometer wrenches are stored at 20% of full reading to maintain accuracy. All torque wrenches should be recalibrated at least once a year or more frequently depending on usage.

A torque wrench is a tool used to apply a specific torque to a fastener such as a nut or a 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. This permits proper tension and loading of all parts. A torque wrench uses torque as a proxy for bolt tension. The technique suffers from inaccuracy due to inconsistent or uncalibrated friction between the fastener and its mating hole. Measuring bolt tension (indirectly via bolt stretch) is actually what is desired, but often torque is the only practical measure that can be made.

Torque screwdrivers and torque wrenches have similar purposes and mechanisms.
