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.
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.
Torque wrenches are precision tools and should be treated as such. Although most micrometer wrenches have a reversible ratchet head, they really should not be used as a ratchet, and especially not as a breaker bar. Most people who break their torque wrenches do so by trying to loosen an overly tight bolt with it. This overly stresses the internal mechanism, causing it to break, especially if the micrometer isn't set to a higher torque value than the pressure that is being applied.
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.
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.
