Description
Overview:
The MaxSteel Adjustable Wrench 300mm by Stanley is a robust hand tool for tightening and loosening hex and square fasteners on construction equipment, vehicles, plumbing systems, and general machinery. Made from forged alloy steel for strength and longevity, it delivers precise adjustment and dependable grip. At 300 mm (12 inches) long with a 39 mm jaw capacity, it provides solid leverage while remaining manageable in the toolbox or on the belt. A narrow head helps in confined spaces, and the bi-material handle offers a secure, comfortable hold during extended use. The laser-marked jaw scale supports quick, accurate size setting in both metric and SAE. Suitable for trade and DIY. Model references: 0-90-950 and STA090950.
