The correct terminology is "Robertson". Thank you for quoting his name.This technology would be world renowned if Henry Ford could admit he was wrong. He blackballed Robertson because he had the money to do it. Ford tried to obtain the patent and Robertson stated he would share the technology, but wanted to retain the patent rights. This is the reason the USA does not have all access to the most efficient screwhead interface of all time. I know the rebuttal was torx. Good luck with a speck of dirt in there.Anonymoushttps://www.blogger.com/profile/04816701575288341161noreply@blogger.comtag:blogger.com,1999:blog-1627331616161641107.post-28682339726523280312016-01-05T03:45:50.258-04:002016-01-05T03:45:50.258-04:00Hey Bob,

Every so often they used to run $1 shipping specials, but alas, no longer. Luckily, I stocked up on a few sized a couple of years ago. I'm not paying $7 shipping for $10 worth of screws. <br /><br />I think that perhaps I have had Amazon prime for so long now that it has skewed my perspective. I'm too used to shipping being free and very, very, fast. <br /><br />I think that the best thing about square drive screws is how well they work in an impact driver. It kills me when the bit slips out of the screw and mars the surface of whatever I'm building. With the square drive that almost never happens.<br /><br />I hope you're well. Happy new year!<br /><br />Jonathan<br />benchblog.comAnonymoushttps://www.blogger.com/profile/10782595710674279732noreply@blogger.comtag:blogger.com,1999:blog-1627331616161641107.post-41188010750443595472016-01-02T05:23:11.269-04:002016-01-02T05:23:11.269-04:00I've been using Robertson screws since I first...I've been using Robertson screws since I first saw them in the woodshop in Norfolk Va in 1992. I learned about the taper in the bits the hard way. I still use slot head screws but only in brass and mostly for the look. Everything else is 'square' drive only. Or here in the states the idiotic square/philip head combo screws.Ralph Boumenothttps://www.blogger.com/profile/10606484453109932074noreply@blogger.comtag:blogger.com,1999:blog-1627331616161641107.post-28502744977623816982016-01-01T19:23:49.367-04:002016-01-01T19:23:49.367-04:00Hello NZ Pete

I find with the Phillips/cross head screws it's easy to use the wrong driver head. the only time a Robertson will cam out is when the driver tip becomes worn, even then they still drive better than the other screw heads.
