Actually, maybe not 3/16. More like 3/32. And the bolts were aluminum, not steel. That for sure was my fault, but it didn't take much to snap off. So now it's drilled out and tapped to clean out the threads. Everything's fixed and ready to mount up in the plane. I really shouldn't have said BME is a joke, but they did let a lot of customers down with the 115. If you buy a Chinese knockoff you know there's going to be a few issues, you get what you pay for. But buying from a reputable American company, the only thing you should need to know is how to tune the engine and fly lol!
