I thought this was an interesting video about the history of the Phillips screw head.
I have a question for our Canadian brothers, did Ford every use the Robertson head bolt in Ford trucks? I know it is used in the pickup and panel truck bed bolts but was it used anywhere else in the Canadian build Fords and Mercurys? From this video it sounds like the Robertson screw head is a dominate head.
I've never seen a Robertson screw, nor have I heard of one.
Phillip head screws look better for trim on vehicles but when it comes to torquing a screw you can't beat a Robertson head. If you start stripping the head of a Robertson it's because the bit is worn..
I'm surprised he didn't mention the Japanese JIS "Phillips head" screws. They look really similar but have a different profiles. That's why Americans who work on Japanese motorcycles frequently round off the heads trying to disassemble them.
I could watch him all day long. Very interesting. ....
He is a great speaker and covers interesting topics. One of his best IMO is this one about passenger pigeons. I thought I knew their "story", but I only knew a fraction of it.
Very interesting. I’ve used Robertson deck screws and on some headlights in 70s cars, but I never knew they were the standard in Canada.
He mentions auto manufacturers used Phillips in the late 30’s, but my 48 is filled with flatheads. I know it’s not vintage, but I’m replacing many of them with Phillips or torx stainless.
Very interesting. I have used Robertson screws for years but always knew them as Square head screws, not to be confused with (external) square head lag screws.
I am a retired Canadian carpenter; most hardware packages we get here come with phillips screws, some of very poor quality, when finishing a house my routine was to chuck them all and use robertsons, not the slightest bit of confusion in my mind about it. My 51 Mercury truck and 50 Meteor car used phillips and straight blade screws. It is difficult to find phillips in a "finish" grade for trim here, wood or metal, unless at a bolt supply house, drywall screws are phillips here but that is about it. I am quite surprised they are not common south of the border!
It’s interesting in the video that by 1950 philips head screws seemed to be pretty common and used by ford. I wonder why there was still a mix of slot and philips on the F1’s. Even the screwdriver in the tool kit was slotted?
