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."
If you are buying a torque wrench for your car, you should buy a 1/2 inch square drive tool, as 3/8 in drive tools only work on lower torque settings (typically below manufacturer's specifications). Adapters are available to reduce the 1/2 inch square drive to 3/8 inch square to fit the more common socket size that most people have.
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.
Owning the right tools can save much time when you are planning a major do-it-yourself project or home improvement project. Adjustable wrenches can make the job simple as you need not have to stop your work mid-way and buy more tools. These are useful tools for the person who is prepared to undertake repairs on his own. The adjustable wrench is an important home improvement tool which is the staple in a tool kit. Basically, they are of three types. Generally at least one of these can be found in most homes. Many people prefer to invest in all of these varieties as they consider them to be great tools for undertaking repairs quickly.
