Re: Fastening plywood in a bus
I had a similiar experience with TEK screws when trying to fasten my plywood to the metal floor. The wings on the screws were causing the screws to strip out. At $8 bucks a box for the small screw count I was a little perturbed. I ended up grinding the wings off each of the screws, pre-drilled all of my holes and used them still to fasten down my plywood. Yes, it defeats the purpose of self tapping, but I will say they did hold tight very well.
