@dlearl476 posted:Crazy synchronicity: there's an article in this month's R&T about phillips vs Robertson. Haven't read it yet.
So I just read the interesting article. Apparently we have Nazi-sympathizer Henry Ford to thank for all those countless hours we've wasting drilling out stripped Phillips head screws.
Mr Roberston patented his square-drive bit in 1907 and subsequent Canadian-built Model T's were so equipped, until Mr Ford refused to pay the vig, and subsequently used the new-fangled Phillips bits.
And the rest, as they say, is history.
I tell yah, it's a crying shame you can't easily get Roberston bit tek-screws, machine screws, etc. I'd convert my entire car to them. I did buy 2 Whia bit drivers and I use those in all the hex/Phillips hose clamps I have, as well as all my Dellorto (slot/hex) mixture screws.
