I cannot locate among my (considerable!) assortment of tools a box spanner or plug socket spanner....nor even a big socket to fit an 18mm plug! What A/F should it be....Daft question, but I don't like using an open end spanner on plugs

Purely because it was available I used a 1"AF deep socket.
Possibly foolish question but, why didn't you just measure the plug AF??

If the plug is an original detachable type, then a 9/16 Whit will fit . If it is a modern replacement Champion D16 then a 7/8th AF (or 22mm!) will fit.

My calliper has died & I haven't got around to putting a new battery in....DOH!
Hedd,
Adjustables are the spawn of the devil as far as I and my knuckles are concerned!

Thanks for that information...naturally I have ancient & modern (NGK) plugs (not at the same time!) so will look out for a 22mm (and a 9/16BSW for the old 'uns).

I use a 22mm combination spanner (ring end) without problems.

Would you believe it "Her who must be obeyed" refers to my Ruby as the toy.

You need to invest in good quality ones.

If you have to use a shifting spaner, first check if it is metric or imperial... 

   

Then check if it has a left or right hand thread...

   

Then the chances of you skinning your knuckles should be much reduced.
