McMaster 4019N15 Black-Oxide Steel Adjustable Wrench Plain Grip, 12" Overall Length, 1-1/2" Maximum Jaw Capacity

Twist nuts and bolts of various sizes with a single tool that will last for decades. To adjust the width of these wrenches, just spin the thumbwheel—the precision-ground jaws effortlessly glide inward and outward. They won't wobble once in place, so you get a stable grip at every size, every time. All wrenches are drop-forged from alloy steel or stainless steel for durability.

Black-Oxide Steel—The dark, matte coating won't wear down or flake off as easily as painted steel, but only resists occasional moisture.
