I need to hang my son's dart board cabinet in the basement, which is finished out but was done using steel studs instead of wood. This dart board cabinet is surprisingly heavy -- like 25 or 30 pounds. It has two holes 16" apart which would be perfect if I was going into wood. But what about going into steel studs? What sort of screw or fastener would I use to mount something heavy? I've mounted other things and it felt like you couldn't tighten things up without stripping the screw in the steel. It's not like you'd put an inch and a half into it like you would with wood. What do you use to mount heavy things into steel studs? And will they hold it up okay? I've been googling around and saw one person have a shelf unit warping the steel on one side and pulling right out of steel on the other. Thanks, Tom

Is it ok to substitute 10d nails for 16d if I increase the number of nails I use?
