Hi all;
Whats the thread used on scaffolding couplings?
I have a 1/2" BSW tap that seems to run in the nuts but suspect it may be 12m? As this is somewhat easier than I think it should be.
I have many coupling that need a nut die down them to clean my stock up with.
Regards Ian
I dont know the answer, but if you have a tap, put it alongside one of the bolts and see whether the threads interlock. 1/2" Whitworth has 12 threads per inch whereas 12mm has approx 14.5 - so if the thread on the bolt is a bit finer than the tap, it may well be 12mm.
