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.
Three of the most common wrenches found in American homes are the pipe wrench, the adjustable wrench and the combination wrench.
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."
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.
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.
