Right, yeah, that exact thing happened to me with a set of hinges I was selling. I had them listed as "heavy duty" which I thought was enough, then a guy messaged me saying they were too light for his gate and asked for the gauge of the steel. I didn't even know what gauge it was at first so I had to go measure them with a caliper. After that I went back and put the thickness and the exact weight limit on every single hardware item I had. It's wild how one tiny missing detail can make you look like you don't know what you're talking about. Now I just assume people need every single spec written out or they'll call you out on it.
