Of the two types of torque wrenches, the micrometer wrench is definitely the more accurate. Typically, they are rated as being accurate to four percent of torque set. However, this accuracy can easily be lost if the wrench is not reset to zero before storage. Beam wrenches don't have this possibility of losing their accuracy, but are less accurate right out of the box. The accuracy of these beam wrenches is typically 12 percent, but can be less on higher torque settings, especially if the operator's hand is shaking from the pressure they are applying.
The Pipe wrench Otherwise called the Stillson wrench, this wrench mostly finds use among plumbers. This tool can be very convenient to use when working in a tight spot where the need for gripping power of an adjustable wrench is most needed. The tool has rough jaws with which it can securely hold the pipe. The pipes can be fitted easily using this wrench as the jaws will help the pipe to stay in place firmly.
When tightening a bolt to the proper torque, it is essential that your hand which is pulling the wrench is cantered on the handle of the wrench. Having it too close or far from the socket actually affects the ultimate torque value you are tightening to. Moving your hand closer to the socket reduces the total "foot-pounds" of torque you are applying, while moving it away, closer to the end of the wrench increases the "foot pounds of torque you are applying."
You will not find an auto repair shop, an automotive training course or even an auto mechanic school that is not well stocked with a wide variety of combination wrenches. When it comes time to do car repairs or other basic mechanical jobs, the first tool in your kit should be the combination wrench. Solid, basic, sturdy and dependable the combination wrench doesn't have moving parts and is designed to withstand impacts on even the most demanding jobs.
Three of the most common wrenches found in American homes are the pipe wrench, the adjustable wrench and the combination wrench.
