Ans: A torque wrench is an invaluable tool used in any field that requires precise tightening of fasteners. It’s a type of wrench designed to apply a specific amount of torque – or turning force – to the head of a bolt or nut. The idea behind using one is to prevent over-tightening and ensure your work’s safety, reliability, and accuracy.
The most common type of torque wrench looks like a ratchet with adjustable settings that read out in units such as “inch-pounds” or “foot-lbs” (or metric equivalent). To use it, you set the desired amount of torque on the handle, then insert the head into whatever fastener you’re working with and turn it until it clicks – just like when using other types of wrenches. This click indicates that the proper amount of pressure has been sustained to meet your preset setup choice, so you can be sure that your job will be done correctly every time.

Torque wrenches are available in various sizes for different tasks, from large ones for automotive repair jobs down to smaller ones for delicate electronics parts installation where precision counts. They come as manual tools operated by hand and powered versions with batteries or electric motors supplying extra muscle when needed. Their adjustable heads also make them suitable for tight spaces where there might not otherwise be enough room for another type of wrench due to size constraints.
In summary, if precision matters in achieving success with any task involving bolts and nuts, then using a torque wrench is essential – which makes it an indispensable part of workbenches worldwide!
