What is an "open-end wrench"?
An open-end wrench is a tool used to tighten or loosen bolts and nuts. It has a U-shaped, open-ended design that fits over the flat sides of a bolt or nut. This allows for quick use, as the wrench can be easily placed and removed. It is commonly used in mechanical, automotive, and construction tasks, especially when working in areas where a full rotation of a box-end wrench is not possible. Open-end wrenches come in various sizes to fit different bolt or nut widths.
