These are good 13mm strong short wrenches. I recently needed two of these to attach the humidifier's top and bottom water solenoids. I had to use a small crescent wrench with what I had at 13mm. I couldn't believe that among all the tools I only had a 13mm open-end wrench. But now I also have these two and they are hanging in my oven room until I need them the next time.
