Yes- 3/4" thread, 1_1/16th across flats!
No! "elancoupe" said a 3/4"
socket fits. That isn't standard!!
Actually elancoupe said
"I am thinking that 3/4, or 19 mm will work."My guess is he was thinking of a 3/4 BSW socket (which is actually about 1-1/4" across flats) what he should, perhaps, have said was
5/8" BSW, which is 1-1/16" across flats and fits perfectly. My error was to repeat the 3/4" rather than checking. I have no idea what he meant by suggesting 19mm.
My excuse- I dealt only with SI units during the formative years of my Engineering career, our parent company was Philips, based in Holland.
It was only later that I came across the dog's breakfast of English "Standard" threads: BS Whitworth, BS Unified National Fine, BS Unified National Coarse, BS Unified National Extra Fine, Bristish Standard Pipe (both tapered and parallel) British Association, British Standard Fuel, British Standard Buttress, British Standard Brass, British Standard Cycles (all three types), British Microscopical Society, BS Aerospace... don't even go there they have their own book, Medical Bone Standard, Fire Hydrant Standard... gasp... now the American "Standards" all measured in inches........
It seems an unlikely circumstance that our original poster has a steering column with a turned-down end section with under-sized thread. Has anyone else come across this?
Happily-retired Chartered Mechanical Engineer, btw.
