Need a couple of nylon washers......

[The Dotties]

And I would like to know what the M number relates to that they seem to sold as.
The diameter of the hole I need is 26mm or slightly larger. Could somebody give me a clue as to the M number please, or is it a direct comparison?
(I’m buying from Internet)
Cheers. Geoff.

The just a shortened way of saying millimetre thread diameter, so if you require a washer for a 26mm thread diameter not the bolt head size then you require a M26 washer.

Usually refers to inside diameter in millimeters. So M5 is a washer with 5mm hole.
In larger sizes you may not get the exact size. Usually advert gives OD and ID. Outside Diameter and Inside Diameter.

Probably M26 which is a little bit bigger than 26mm

Best to just measure...... Oh beaten to it....

I was guessing that was the case, so thanks to all for confirming.

Tidying up toolbox and sorting Dad's stuff out, separating metric and imperial again. Surprised how many BA sockets and spanners we had accumulated over the years.
