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.
Toolkits come with a variety of selections from a basic 8 piece wrench set, on up to 16, 32, 64 or even 256 piece or more sets. While a few common wrenches will cover most tasks, having a large toolkit with a full selection of wrenches insures that you are ready for any job that comes your way.
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.
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."
You can think about the purpose of the tool before deciding on the kind of wrench to meet your requirements. Adjustable wrenches are handy tools in a home and you can invest in each of these varieties to undertake all types of repairs in your home quickly and easily.
