Drum brake retaining screw thread size

Post by martinclan » Mon Sep 27, 2021 8:42 am

Does anyone know the thread size for the drum brake retaining screws?
Somewhere in the back of my mind I have a feeling it is something odd like a BA thread....

Cheers, Robin

Thanks Chris
That's what I wanted to hear. I can get them from a nut and bolt store rather than pay the inflated prices from one of the classic car spares places.

Just make sure the counter sunk screw head is flush with the outer face of the drum or you will loose wheel studs then the wheel!
