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."
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.
Combination wrenches are available in a wide variety of sizes for both standard and metric nut and bolt combinations. This simple hand tool does not require electricity, is designed specifically for the job that it is made to do and is highly resistant to breakage.
Most manufacturers of torque wrenches supply them with a plastic storage box to protect them. They also often come with the 1/2 inch to 3/8 inch square drive adapter; some even come with a drive extension.
