The use and technical characteristics of open-end wrench

Screws are the main fasteners in mechanical equipment. Open-end wrenches are important tools for processing, production and maintenance in the machinery industry. This project is a revolution of traditional wrench tools. It has the following advantages. 1. Works fast, working three to four times faster than traditional wrenches and faster than a quick wrench. 2. An open-end wrench can be used for 2-6 kinds of screws, while a double-ended wrench can only be used for 2 kinds of screws. An open-end wrench is equivalent to 2-3 fixed wrenches, equivalent to an adjustable wrench but can work quickly without adjusting the opening. 3. It has a long service life and cannot be broken, and the front quick wrench is easy to break. 4. The manufacturing process is simple, and its cost is lower than that of a dumb wrench. 5. Light weight, easy to carry and labor-saving
