Chevrolet horn button screws

[David Dunlop]

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.
