The tool on the cover of Mac OS X Hacks is an adjustable wrench. Wrenches are used to hold and turn nuts, bolts, and other threaded parts. While fixed wrenches have stationary jaws that are forged to fit a particular size of nut or bolt head, adjustable wrenches feature sliding jaws that open and close to suit many different sizes. For this reason, the size of a fixed wrench is always expressed as the capacity of its jaw, while the size of an adjustable wrench is usually expressed as the length of the tool. Adjustable wrenches vary in size from 4 inches to 2 feet in length, but 10-inch or 12-inch wrenches usually work well for most household tasks.

Fixed wrenches offer more precise control over specific tasks, since their stationary jaws always remain tight. Adjustable wrenches are ideal for jobs that call for a variety of wrench sizes in circumstances that limit the number of available tools.
