Chevrolet horn button screws

Slotted head = hand assembly.
Phillips or square = powered assembly.
The flat faced c/s screw top looks so wrong in that situation. It has to be the oval head c/s.
(all aesthetics and my opinion)

Regarding Robertson (square drive) screws in Canadian service or Canadian Automotive, I can think of very few examples of either. I have seen screws on some of the Bren chests that were a combination of Robertson and slot drive. Most of my run-ins with Robertson are with various crates or locally produced wooden items.

Rob, I wasnt saying that square drives were used in WWII. To me they are a modern thing.

I was more referring to David's post.



These days, any visit to Canadian tire or Home depot for machine screws or self tapping screws (aside from drywall screws) inevitably leads to only Robertson being available if using SAE threads. I have had to use metric in the past in order to get slot drive.

Rob, have you tried McMaster-Carr? UNC, UNF or metric

Believe it or not, McMaster Carr will not export to Canada (this may have changed but I have not heard otherwise).
When I find boxes or jars of old steel, non plated, slot drive screws at the surplus places, I buy them. My inventory is decent enough that I rarely have to order them these days. And when I do need old time fasteners, Blacksmiths bolt and rivet supply in the US is my go-to place. They do not sell torx, robertson, phillips, their hardware is non-plated and usually chemically blackened. https://www.blacksmithbolt.com/

Thanks Rob, another good place of supply.

If you ever need something from the USA that the supplier will not send to Canada (like McMaster Carr), talk to me: I'm happy to act as 'post office' and send whatever it is on to you. Might mean double postage, but at least you'll get what you want/need.

The president of McMaster Carr did hard time in crowbar hotel after his company sold wrenches or fittings of screws to some place on the US State Dept list of really really bad places.

We've had lots of posts on MLU about McMaster Carr over the years. Drool-Worthy Catalog, but will not ship to ANY overseas destination, not just Canada. Even using a foreign credit card to place your order (with a US delivery address) will get your order cancelled. Their fingers must have been very badly burnt by past experience, and they are not keen to repeat the lesson.

And this is the sort of rivet counting conversation that makes our hobby interesting? Now the question is not just how many screws but pitch, thread, length and head.

FWIW, in Kandahar I was in a 4-eyes intelligence office lodged in a plywood hut. The commander was a US Navy three-ringer intelligence officer who had many interesting stories. I was asking about the building and we got talking about which of the US services gets things done in various circumstances. I commented that the electrical panel had been installed by Canadians. Huh? How on earth could I know that? See, Robertson heads on all the hardware.

(In his eyes every Canadian soldier had been something else before he met them, and scratch one and you'd find a former paratrooper in a Navy uniform doing imagery analysis, or university educated former clerks doing maps, or Cpls who were serious tech geeks.)
