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.
The right mechanics tools make the difference between an easy job and a difficult one. A mechanic or carpenter is defined by their tools and having the highest grade tool set, complete with combination wrenches, prepares you for any job. The complete mechanics tool set includes wrench kits for automotive jobs, bicycle repair and even specialized work involving foreign automobiles and RV repair. Accessories for spanners that you may want to add to your tool set include cases, wrench grips and wrench holders.
There are two basic types of torque wrenches on the market, what are called "beam" wrenches and "micrometer" wrenches. Beam wrenches count on the built-in flexibility of any material. As torque is applied, the wrench flexes, while another rod, with a pointer at the end, indicates torque being applied on a scale.
Most manufacturers of torque wrenches supply them with a plastic storage box to protect them. They also often come with the 1/2 inch to 3/8 inch square drive adapter; some even come with a drive extension.
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.
