The number written on a Spanner shows size of the head of a bolt (or nut) that it is to be used on.

Quite often, really.

Does the bolt size refer to the diameter of the bolt, not the size of the head?
Your fault Motman....see what you have started.!..why not suggest measuring the pipe with a laser and measuring the time light takes to cross the pipe,or use soundwaves etc etc...might be more up the OP's street.Vernier gauge or failing that, an open ended spanner - try a 10mm and 15mm.

Rofl.....IndeedCut a bit off and take it to a local plumbers merchant and ask for two stop ends. Ideally go in on a Saturday 10 mins b4 they close. They like that.
Seems to have kept you busy,this forum,contribute more often!A little history behind this - my neighbour (who has learning difficulties) called me in a flap yesterday as water was pouring from the radiator on to her kitchen floor. I whizzed round and turned her water off and drained the system and then took photo of pipe, and then asked question here. To be honest I was just expecting a quick answer from the 'experts' not war and peace and a UN debate. That said I removed the radiator replaced it as well as the valves and all is working fine and no drips - The pipe size was indeed 10mm. Thank you to those who contributed.
He's fixed it now. Perhaps he used a ring spanner on the pipe?How's he going to tighten a round pipe with a spanner?.....
