I think the "U"Drive Screws came out in the 1930's, maybe later. The threads were rolled on using two dies. The Round Head Drive Wood Screws probably date to the 1950's. when I started in the 1960's there no wood drive screws in inventory. I only had one request for those in the 1970's. And that guy was reproducing an antique piece of furniture. I think the minimum order of 100,000 screws turned him off.
