tried out the Robertson screws he found they saved considerable time in Model T
production, but when Robertson refused to license the screws to Ford, he realized that the supply of screws would not be guaranteed and chose to only use them in Ford of Canada's production.
Robertson's refusal to license his screws prevented their widespread adoption in the United States, where the more widely licensed Phillips head has gained acceptance. However, an alternative explanation for this preference (that has even been aired on a History Television
) is that Americans simply preferred their own invention as opposed to the "foreign" Robertson screw."

I like them a lot more than the Phillips. Robertson really screwed himself by not licensing Ford.
