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.
When storing your wrenches, a tool storage chest, wrench holder or a standard tool box can be useful. Tool boxes and cases for wrenches, include soft cases in rollout and box style, as well as heavy plastic cases or even heavy duty steel, titanium and aluminum toolboxes for the serious mechanic. Wrenches can be stored in tool chests, roll up cases, and will help you find the exact tool you need for getting extra leverage on a stubborn bolt.
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."
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 everyone who has been through an apprentice program knows, bolts are used in construction, manufacturing, and assembly of almost everything. By having a combination wrench set at the ready, you can show that you have the ability to place or remove a bolt easily and efficiently.
