My shroud have a shape to take a spanner when adjusting the bottle screws.

An 11mm spanner is just slightly too big.

What size tool should be used?
An adjustable wrench might work okay but I find they are a nuisance to use.
 
13/32” is the next size down. Or, if you must you actually can get 25/64”:

I found these very good, probably overkill for single use but they come very handy in a number of cases.
ps just in case: it s a different tool from the usual generic long handle grip pliers (whatever their proper name), the two jaws are flat and move in parallel, basically it can adapt to any size bolt/nut etc

In a thread some months ago I got hammered for suggesting an alligator spanner or anything, like a Mole grip, adjustable, pair of pliers etc - the overwhelming suggestion was

Use a spanner.

Does not answer the OP - but maybe he needs an Imperial size not metric.

I like the idea of taking a spare spanner and grinding it to fit - and then keeping it for the specific task. I had a big socket whose only use was removing a Volvo prop - why not a dedicated spanner for rigging?

Why would they make rigging with flat sides that do not fit standard spanners?

If its meant to be 11mm it should be 11mm.

What is A OBA?

Probably the best suggestion is to grind a 10mm wider to fit

But that's a fairly dumb size for the flats on a rigging fitting. It's just going to mean everyone will use adjustable spanners and risk rininging off the faults, or slipping and hurting their hands with ill fitting spanners.

Zero BA, an Olde World size

Only those of us who had to deal with all these different threads and spanner sizes know! Olde World describes it perfectly.

My 1930 Rudge motorbike had 9mm across flats nuts holding the cylinder down. 5/16 X 26 cycle thread but much reduced diameter nuts because of reduced clearance to the cylinder side. Good thing there were plenty of them!

Water pump pliers, AKA channel locks (more or less) though those might be a better proprietary variant and would probably work if the fitting has ever been lubricated.

If not a Stilson will shift it.

But as this is something you'll likely be doing a lot, worth getting an open-jawed spanner that actually fits.
 
Just seems. Odd that they don't make the end. Fittings a metric size. Boat is German from 2001.

It is a 21st century boat.
Why, have rigging components not converted to metric??
