About Adjustable Wrenches
Adjustable wrenches are some of the most versatile tools in the toolbox. Often called a spanner wrench or crescent wrench, these tools are used to tighten or loosen a nut of bolt simply by tightening the expandable jaw. The variety of sizes make this great for plumbers as well as do-it-yourselfers. If you typically over twist your nuts and bolts, use a torque wrench or precision torque wrench to better control the amount of pressure applied. Sold individually or by the set these wrenches can be found in black oxide, chrome, satin or powder coat finish. Spud wrenches are also adjustable and are used in heavy mechanic work as their tapered handle also serves as a tool that can be used to align bolt holes.
