An adjustable wrench is an essential tool for any DIY home mechanic or handyman. The beauty of this tool that it is not limited to a single specific use; it can be used for many different size nuts and bolts. Being adjustable it is also not limited to metric or imperial sizes. Additionally these wrenches are typically much longer than regular sized open ended spanners, so they can provide much more leverage. The ToolPRO 250mm Adjustable Wrench is a heavy duty tool with a satin black finish and also includes Metric size markings on the jaw opening.
