Now that we are on topic of screws , I feel very badly for our US neighbors. If you only had the opportunity to use one Robertson screw in your life you would never go back to a Phillips head screw again. Robertson screws are not infallible but they are at least 1000 times a better head than Phillips.
Us Canadians hear that the only reason the US does not move over to the Robertson head is because it's a Canadian invention (just hear say) but for what ever the reason, I feel sorry for you every time I work on an aircraft. I use Phillips on my aircraft because they are aircraft certified, I'm sure Robertson head screws could be made to the same mil spec.
At work we routinely (and I'm very serious here) through out all the Phillips screws that come with components and replace them with Robertson, they are just that much better.

slight thread drift?...yes, I throw out all my slotted, and most Philips, unless they are in my 'airplane' section of the yard!
I heard that none other than Mr. Henry Ford, master of efficiency and control freak, wanted a screw that could withstand being driven by machine into the ( wooden) body frames of the model T etc.
He found the Robertson superior in every way, but the savvy son-of-a-Scot would not sell the patent to Ford, he insisted on licensing the design. History shows that Henry would have none of this, and bought the rights to the Phillips head instead.
oh my, what HAVE you done Mr. Ford????????????
