I believe there were two different kinds of screws that were used depending on the type of steering wheel. If it was the early molded wheel a pair of self threading screws were used with a course thread. These were the screws that came in my NOS GMC horn button kit. The other style were oval head machine screws. Off the top of my head I believe they were a 10-24 thread. I’ll have to check what I used on the wooden CMP steering wheel in my C15a

I looked at the horn button assembly on my C8.
I am 99% confident the screws are original factory fitted .... but who knows I can't be too certain ? My hunch was correct, the screws are C/sunk head with a domed top, not flat. The pressed metal ring has holes that are shaped to accept the C/sunk shape. Those round head screws in Jordan's NOS GMC kit look to be too short for a moulded GM CMP steering wheel plus the round head shape, just doesn't seem they would fit the pressed ring correctly.

On the basis of the style of screw alone, the ones Marty has posted a photo of scream post war American replacements, if they came out of his C8A.
To my knowledge, the wartime rule of screws used in Canadian manufacturing was slot head. Post war, the USA went big time towards their Phillips head whereas Canada preferred their own square Robertson design. Also the screw thread on Marty’s is far too fine when compared to the other photos of originals with a coarser thread. It may be possible to restore the threads chewed out by the replacement screws. If the anchor material is Bakelite, clean it of dust and wipe the old hole with a thin coat of epoxy and let it cure a week. Then slowly screw in correct screws until they just snug up. If metal base material you can heat it and wipe with solder in the same way with same result. David |

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 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.)
