I sometimes use those blue plastic coated bolts that you drive into holes drilled into the concrete. But they are too large, and I don't want those bolt heads sticking out of the threshold.
I heard there are nails that can be drive into concrete, are they available at hardware stores? Also if I drill a hole, can a regular screw be driven in there and hold?
