What is the main purpose of an open-end wrench?

• A. To grip small items
• B. To adjust valves
• C. To tighten or loosen bolts
• D. To hold fire hoses

Answer: (C)

An open-end wrench is specifically designed to tighten or loosen bolts and nuts. Its open ends allow it to fit over the flat sides of fasteners, providing a secure grip while turning. This versatile tool is commonly used in various mechanical and plumbing applications, making it essential for tasks requiring the adjustment or assembly of parts using fasteners. While other tools might serve different functions, the open-end wrench's primary application is the manipulation of bolts, which makes it invaluable to situations where assembly or disassembly is needed, such as in vehicle maintenance or when working on machinery. The design of an open-end wrench allows for better access to confined spaces where a socket might not fit, enhancing its utility in various repair and maintenance tasks.
