I've been meaning to post on here asking if anyone knows where to get the Robertson screws, which aren't exactly the same as the square head screws in the U.S. I have the optional armoire in my 99D190P, and it's missing several of the screws. It hasn't been a problem until the past 3 years, in which the door has started to sag. It's sagging to the point that I had to put a shim behind the latch so the door would stay shut, but now it's still coming open while driving, so I need to replace the missing screws. Does anyone know where I can get the Robertson screws, or are people on here just using Phillips or square head screws?
I did find out some trivia about the Robertson screws, however. Henry Ford wanted to use those in his cars since they were superior screws. He wanted to get a patent in the U.S. on them though to prevent his competitors from using them, but Robertson wouldn't agree to that. So Ford used Phillips screws instead, and apparently the rest of the U.S. just went along with those!
