Adjustable wrench

An adjustable wrench is a versatile hand tool that can be used to grip and turn nuts, bolts, and other fasteners of various sizes. It is one of the most essential tools for any toolbox, as it can be used for a wide range of tasks, from simple repairs around the house to more complex mechanical work. Here are the key parts of an adjustable wrench: Jaw: The adjustable jaw is the part that grips the fastener. It is typically made of hardened steel and has teeth on the inside to prevent it from slipping. Screw mechanism: The screw mechanism is used to adjust the size of the jaw opening. It is typically located at the top of the wrench, and it has a knurled knob for easy adjustment. Handle: The handle provides leverage for turning the wrench. It is typically made of metal or plastic, and it may be ergonomically designed for comfort.
