When making use of a torque wrench it is vital to be in possession of a complete understanding of how to use the precision tool in the correct way, not only to ensure accurate results but also to avoid damaging the device or causing injury to yourself. 

The good news is there are some simple rules that are easy to follow that will make sure that torque wrenches can be used safely and in such a way that will guarantee their longevity. 

Helpful Tips

The first thing any newcomer to using a torque wrench should do is to make sure they have read their instruction manual. It is vital to wear goggles or safety glasses at all times while using the tool. To apply torque, the torque wrench should always be pulled rather than pushed, with the user altering their stance accordingly to avoid falling. 

Torque wrenches should never be used with fasteners or sockets that display cracks or any other signs of wear. The ratchet mechanism could break or slip if its parts are dirty, worn, or mismatched, making it of vital importance to inspect your torque wrench before using it. 

Another good tip is to make certain that the direction lever has been completely engaged on the ratchet. Mechanical torque wrenches are all calibrated from between 20 to 100% at full scale, and it is, therefore, crucial that they are never used over or under those limits. 

To work out which torque wrench capacity would be best to use for an application, there are a number of factors that need to be taken into account. However, a general recommendation is to make use of a torque wrench within the middle 50% of the tool’s overall capacity. This will make the tool easier to use for the operator, increase the accuracy of micrometer adjustable torque wrenches and also result in a much longer lifespan for the device. 


The handle of a torque wrench should always be firmly gripped in the middle of the grip, and the final torque should be approached in a slow and even manner. When the target torque has been reached, pulling of the wrench should cease straight away.

After using the torque wrench should be correctly cleaned and then stored. Wipe the torque wrench to clean it, but never immerse it in liquid. Micrometer adjustable torque wrenches need to be stored while set at the lowest possible torque setting and the handle should always be unwound after use. 

If a torque wrench is dropped at any time then it will need to be recalibrated. Micrometer adjustable torque wrenches need to be exercised no less than three times at 100% of their full scale before being used. 

Torque wrenches need to be calibrated to the specified torque units and should be given to a qualified calibration limit every 2500 cycles or at least once per year to be recalibrated. 

Torque wrenches are a special tool used for tightening bolts and nuts on particular levels, making it important for them not to be damaged so that they will continue to give accurate results.
