Re: An explanation about the Robertson screw
Herb - I saw that too, very interesting. Seems like they’re potentially missing some time between 1913, when this screw was first used, and 1932/1935 when the Phillips head was invented by Thompson and patented by Phillips. The Phillips head screw would have never been used on a Model T like the video implies.
