I'm probably the 1000th person here to go looking for this screw, but I need to know what it is. Since it is off the ancient MG style door latch, I assume it is some British thread, but it doesn't match anything I can find in the tables. It measures .1065" major diameter, and thread pitch is about 44 tpi. The "6BA" thread seems close at .11" dia and 47.9 tpi. It is too fine to be a 1/8" BSW (Whitworth) at 40 tpi. A 4-40 UNC is too coarse. Anybody .. Bob?
many thanks,
Sam
