Adjustable Wrench (General Term): A Complete Global Industry Guide

What Is an Adjustable Wrench? Definition and Introduction

An adjustable wrench, also known as a crescent wrench or shifting spanner, is a hand tool with a movable jaw that allows it to grip nuts, bolts, and pipes of various sizes. Unlike fixed-size wrenches, the adjustable wrench features a thumbscrew mechanism that adjusts the jaw opening width, making it a versatile tool for mechanics, plumbers, and DIY enthusiasts. The tool is typically made from chrome-vanadium or carbon steel, with a drop-forged head for durability. Its design allows for quick adjustments without needing multiple wrenches, though proper technique is required to avoid rounding fastener corners.
