Flat DIN125 Washers are the smallest type of flat washer because their outside diameter (OD) is usually just a little more than twice their inside diameter (ID). If you already have a washer and you are trying to match it measure the inside then look for a size slightly smaller that your measurement. For example the inside measurement of the washer you measured is approx 6.50mm you need to look for a M6 washer. If the washer measured 17.25mm internally then you need a M16 Washer. It is aesthetically pleasing to the eye and very practical because of its excellent corrosion protection in most environments. Most products can be identified by the following markings: A2 A2-70 304 or G304 but not all washers are stamped. All material is advisory only and its use by anyone is entirely voluntary.

These washers had "316" stamped into the washers. You don't see that very much these days. I usually have to put a magnet over so-called "stainless" items to make sure.

These are a much better fit on M12 bolts than regular "M12" washers. Minimum I.D. is approximately 12.1mm.
