now i'm confused. One table I'm looking at shows 7/8 AF is 22.22. Another graph shows 22mm is 0.866 inches, oh poo inches not millimetres. It is not 0.009 of a mm it is 0.009 of an inch. 1 inch is 25.4 times bigger then 1mm
how stupid I have been. Looks like I will have to keep my eyes open at the car boot after all for a 22mm spanner
thank you gents for the help and saving me from a disaster
