They cost over $5 a pound and you need either a good arm and lots of patience or a strong powered screwdriver to put them in, but my hubby and I use wood screws in most of our wood construction, especially any framing.
When we close in pipes behind the shower, we make sure we can access them again. That means planning a structural piece that looks good in the finished room and securing it with screws. Because after you do the fix, you can screw it back in again, and don't have to worry about wrecking the look (or structural integrity) by yanking out nails to get in there again.
I've yanked out my share of nails when repurposing wood. It can be hard -- and dangerous -- work. That you can knock lots of nailed together things apart with a few strong whacks of a heavy hammer doesn't reassure you about the structural strength of things put together with nails.
Well, yesterday we decided to dismantle one of the two horsehoe pits we don't use. Out came the 18V cordless screwdriver and out came the screws. Only two were bent; the rest went into the screw box for that size. An hour later we had 4 6 foot 2x 6s, 4 corner posts, a 2 foot length of rebar, half a cubic yard of sand on and under the tarp cover by the garden fence and the area reseeded to clover.
Yeah, we'll just keep screwing around.
