Superwinch, is it ? LT2500

Well went to mount winch to new 2016 570l and was thinking how nice it was being pre-drilled and all when SNAP…mounting bolt broke in half. And this is supposed to be a " grade 8 bolt " ? Anybody have this happen to them ? I know it’s an entry level whinch but come on now, I know it werent me and my 8 inch wrench. The upside was I put around twenty miles on it today, most of it with that new toy stupid grin on my face. Drill it or send it back ?
