I want to bolt my safe to my basement floor. I will be using a piece of 3/4 treated plywood for the safe to sit on, sized 1/2" over the safe's footprint. Counting the thickness of the bottom of the safe and 3/4" plywood, how long of 3/8" concrete lag screws will be sufficient to keep the safe from easily getting moved?
I know most basement slabs are 4" deep, and I don't want to risk going going through the slab, but screw sizes are limited in length, and I don't want them mounted too shallow either.
