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.
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.
Combination wrenches are available in a wide variety of sizes for both standard and metric nut and bolt combinations. This simple hand tool does not require electricity, is designed specifically for the job that it is made to do and is highly resistant to breakage.
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."
An automotive tool set should contain a variety of common wrench sizes to handle automotive repairs while on the road. By having a wrench set in your vehicle you are prepared for any emergency car repairs that may be needed.
