Who makes these screws?

These came in on a show. They work great with fender washers. Hi/lo thread and a button head. Pictured next to a standard 1-1/4" drywall screw.

DRU beat me to it. ITW. I had a maintenance job at the one in Northern IL I would pull these out of my boots on a day to day basis and find them in all sorts of nooks and crannys.

Thanks guys. Ya'll rock.

When I first opened this thread, I only saw the top half of the picture. I was thinking... "Um, looks like a standard 1" drywall screw to me!". Then I scrolled down.

They are similar to Kreg screws for butt joing lumber.

Similar, but you pay out the butt for actual Kreg brand screws. That's not to say I don't love their jig and use it all the time, cause I do.
