A screw wrench, often called a wrench or spanner, is a tool used to tighten or loosen nuts and bolts. It comes in various shapes and sizes to fit different fasteners. Unlike a screwdriver, which turns screws, a wrench grips the sides of a nut or bolt head. Think of it as a key for mechanical connections, helping to assemble or disassemble structures.๐ฉ It's essential for any DIY project or mechanical repair.๐ง
