I'm looking around screwfix for washers and don't really understand the sizes..
for instance
http://www.screwfix.com/prods/17038/Bolts/Washers/Flat-Washers-BZP-M10-Pack-of-100
those are listed as form A, m10
so is that a 10mm internal diamater? If so.. how do i know the overall diameter?
others listed as eg m8x25 .. so is that 8mm internal and 25mm external?
much thanks
