Adjustable Wrenches

The extra-large jaws on this 1 1/2-pound cast-iron plumbing wrench get a secure hold on any fitting a homeowner might encounter: eight-sided nuts, square nuts, unions, and packing nuts up to 2 5/8 inches in diameter. The offset jaws and short handle make the tool more compact than a comparable straight-handled wrench, useful when you're working in tight spaces, such as under the sink. 9 1/2-inch, $30; ridgid.com
