Yes, I have been to Lowe's and Home Depot. Our closest hardware store doesn't really carry much hardware, though. I was there yesterday looking for a 1/4 in. box end wrench. They had NO box or open end wrenches. They sell stuff for urban farmers, mostly. I didn't look for the screw, so I'll go back to make sure.
The one good hardware store we used to have has downsized and mostly sells decorative hardware now. Our metro area has 3 million or more people, you'd think there would be one good hardware store here.
