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.
Three of the most common wrenches found in American homes are the pipe wrench, the adjustable wrench and the combination wrench.
The right mechanics tools make the difference between an easy job and a difficult one. A mechanic or carpenter is defined by their tools and having the highest grade tool set, complete with combination wrenches, prepares you for any job. The complete mechanics tool set includes wrench kits for automotive jobs, bicycle repair and even specialized work involving foreign automobiles and RV repair. Accessories for spanners that you may want to add to your tool set include cases, wrench grips and wrench holders.
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.
