Screws " create less shock compared to pounding on nails."
I'm with ya there. And when you, I mean when I screw up the installation with screws, its easier to take it apart and start over than when I screw it up with nails. Wait... I mean when I nail it down perfectly, I haven't screwed it up and then.... no, that ain't it either. When a lag screw breaks a nail, an emery board....awww screw it!
You're just over tigtening the lag screws. At least with driver driven screws the head usually gets buggered B4 it over tightens, in fact that's one reason Phillips heads were invented. The driver is suppossed to cam out before over tightening or breaking the head off. Of course when the head is buggered or broken off its hard to dissasemble something that got screwed up, or down or.... ummm, I think this is where I came in and every one else left.
