Three of the most common wrenches found in American homes are the pipe wrench, the adjustable wrench and the combination wrench.
Micrometer wrenches are pre-set to the required torque on a vernier scale. An internal spring loaded mechanism measures the torque. When the bolt is tightened to the desired torque it "clicks."
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."
A wrench is an invaluable tool for general repair and maintenance. The grip and mechanical advantage it provides enables the user to apply torque to turn nuts and bolts.
