Overview of General-Purpose Wrenches

Three of the most common wrenches found in American homes are the pipe wrench, the adjustable wrench and the combination wrench.
Adjustable Wrench
Among the most versatile of home repair tools, an adjustable wrench can be used on a wide variety of nuts and bolts.
While the top portion of this tool remains stationary, the screw located at the bottom must be turned to adjust the grip. The movable jaw must be located on the side of rotation to prevent slippage and damage. When dirt or dried grease makes it difficult to turn the screw on the adjustable wrench, simple cleaning-and-lubrication acts as the perfect remedy.
Combination Wrench
A combination wrench is a double-ended tool used to tighten or loosen nuts from bolts. One end of this tool is open while the other is boxed or ringed. Each combination wrench fits a specific bolt size. A set of combination wrenches is sold in multiple size increments.
Pipe Wrench
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.
The most popular among pipe wrenches is the straight wrench, designed by Daniel C. Stillson in 1869. A variation, the offset wrench, is useful in constricted spaces and when the objects that need to be turned are at an awkward angle. The end pipe wrench is used on pipes that are overhead, close to a wall or at an angle where they change direction.
