Micrometer wrenches are pre-set to the required torque on a vernier scale. An internal spring loaded mechanism measures the torque. When the bolt is tightened to the desired torque it "clicks."
Toolkits come with a variety of selections from a basic 8 piece wrench set, on up to 16, 32, 64 or even 256 piece or more sets. While a few common wrenches will cover most tasks, having a large toolkit with a full selection of wrenches insures that you are ready for any job that comes your way.
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.
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.
