A combination wrench set is useful for the aspiring motor mechanic as well as industrial mechanics, carpentry jobs, household repairs, automotive repairs and for common tasks such as furniture assembly.
Metric tools and metric mechanics sets, in addition to standard wrenches, keep you covered for any repair situation. By having an array of metric tools conveniently available you can grab the 8mm or 15mm wrench you need to get the job done, slip it in your pocket and you are ready to go. The roll out case keeps your combination wrenches well organized and ready for automotive jobs or other tasks. In addition to your metric mechanics set, you may wish to purchase specialty manufactured wrenches which can meet the most exacting specifications, including sets that are designed to handle non-standard bolts. A complete set of metric tools for your assembly and repair needs is as essential as a standard tool set which includes the commonly used, 1/4″, 3/8″, 1/2″ and 3/4″ combination wrench.
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.
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.
