Ok, another one. I'm now trying to hang the entry way shelf into studs. I have hooks that can take up to 35 lbs. I have 2 inch wood screws, number 8 width. Does anyone know if there is a weight limit to the screws? In other words, I want to be assured that I won't overload the screws (I am installing at least of them into a stud) and have the shelf come crashing down if I hang my diaper bag from a hook. TIA once again.
