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.
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.
When tightening a bolt to the proper torque, it is essential that your hand which is pulling the wrench is cantered on the handle of the wrench. Having it too close or far from the socket actually affects the ultimate torque value you are tightening to. Moving your hand closer to the socket reduces the total "foot-pounds" of torque you are applying, while moving it away, closer to the end of the wrench increases the "foot pounds of torque you are applying."
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.
Three of the most common wrenches found in American homes are the pipe wrench, the adjustable wrench and the combination wrench.
