Wrenches are fundamental tools designed for gripping, turning, and twisting objects such as nuts, bolts, and fasteners. Their principal function is to apply torque to turn objects, typically to tighten or loosen them. Wrenches come in an array of sizes and styles to match specific tasks, allowing for versatility across various applications. The main characteristics of wrenches include adjustable jaws for different sized nuts and bolts, a firm grip for increased leverage, and durable construction to withstand repeated use and significant force. They are commonly used in automotive repair, construction, machinery maintenance, and DIY home projects.
Manufacturers known for producing high-quality wrenches include Stanley Black & Decker, Snap-on, Craftsman, and Bosch.
