Robertson Screws

Miz B was manufactured in Canada.  Model A's manufactured in Canada in 1931 had Robertson screws.  In 1908, P. L. Robertson began to manufacture a square recess impression in the head of a screw in Milton, Ontario, Canada. At that time, it was a revolutionary change in the fastener industry. The first patent was issued in 1909 and the last patent expired 55 years later in 1964. For his invention, P.L. Robertson screws and screwdrivers carry his name to this day.  When Henry Ford tried out the Robertson screws he found they saved considerable time in car production, but when Robertson refused to license the screws to Ford, he realized that the supply of screws would not be guaranteed and stopped using them.  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.  Just another way my car is different.

We ordered a set of Robertson screws to replace the slotted and Phillips screws that had been put in the car over the years.  Not only did we discover the slotted and Phillips screws, but we also discovered Hex screws!  I suppose, eventually, we will have the car back to the way it was manufactured.  The Robertson screws most noticeable are the ones in the dash rail and in the instrument panel.  I have to find an unusual Hex driver to remove the screws in the exterior door handles.  They are supposed to be Robertson, as well.  

Another uniquely Canadian part we ordered was a Canadian Data Plate.  This will be riveted to the fire wall.  The original must have been removed when the car was repainted, years ago.  Presently, there is no data plate.

Little by little, she will be correct!  Until that day, I am really enjoying driving the little car.  I go everywhere in her!  It takes me a little longer to get there, sometimes, but I always enjoy the journey!
