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.
Crescent wrench The most common type of adjustable wrench found in most homes is the crescent wrench or a wrench with an adjustable end. These adjustable wrenches come in various sizes. A majority of homes have the normal 1 1/2" wrench that can be used to repair any type of faucet or pipe in the house. Large or small projects can be completed easily with the help of the crescent wrench. This angled jaw of the crescent wrench lies perpendicular to the handle at almost fifteen degrees. This tool finds a place in homes because of its ease of use. Most homes use this type of wrench to loosen any bolt or nut that may get stuck. Currently this type of adjustable wrench is used for undertaking other repair work also. Nowadays there are lid openers that incorporate the crescent wrench concept to make lid opening very easy. This type of wrench is also used to secure items such as doors when their faucets or handles have broken.
You will not find an auto repair shop, an automotive training course or even an auto mechanic school that is not well stocked with a wide variety of combination wrenches. When it comes time to do car repairs or other basic mechanical jobs, the first tool in your kit should be the combination wrench. Solid, basic, sturdy and dependable the combination wrench doesn't have moving parts and is designed to withstand impacts on even the most demanding jobs.
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.
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.
