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.
A wrench is an invaluable tool for general repair and maintenance. The grip and mechanical advantage it provides enables the user to apply torque to turn nuts and bolts.
Typically, a pipe wrench is composed of an upper hook jaw and a lower heel jaw, both connected to a flat handle. The lower jaw is adjustable to the size of the metal object. Forward pressure on the handle pulls the jaws closer for ease of gripping and turning. Usually made of aluminum or steel, pipe wrenches are available in various sizes measured by the length of the handle.
Three of the most common wrenches found in American homes are the pipe wrench, the adjustable wrench and the 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.
