An adjustable of the correct size....Hi,
Can someone please confirm what size of nut this is likely to be as it appears I don’t have a spanner big enough:

If you don't have any calipers measure one of the flats and somebody on here will be able to do the maths to work it out!
Thanks, much appreciated - I’m assuming AF is Across Flats? What does BSP stand for?I've just measured a box full of assorted regulators, O2, CO2, propane, argon, and they're all 1.100" across the flats +/- a few thou. The spanner which fits all of them is 1.1295" AF, so nominally 1 1/8". The nut itself is 5/8" BSP.
Yep metric man here.. however I’m getting better with Imperial. I am just 1mm short, but I could of sworn I had a 28mm spanner kicking about…Mine is a 5/8 BSW. 28mm should fit nicely if you're a bit modern!
