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.
As its name suggests, the pipe wrench is used on for the maintenance and repair of pipes of the soft iron variety. A pipe wrench is also used on other fittings with a rounded surface like rods and bolts.
Three of the most common wrenches found in American homes are the pipe wrench, the adjustable wrench and the combination wrench.
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.
