Junter 20pcs M6, 6 ID x 18 OD x 1.6mm Thick 304 Stainless Steel 18-8 Plain Finish A2 Stainless Steel Plain Finish Metal Large Flat Washer DIN9021 (M6*18 * 1.6)

Just regular metric washers. About .5 to 1.5 thick. They are not much bigger then the screw/ bolt head you will be using. So if you want fender washers, keep looking! Has it's own container that is 5 " long, 2 1/2" wide and 3/4 thick. I was surprised how small it is. At least I have washers when I need them.

When it goes outside in east TX you gotta use stainless.

good washers....hard not to be a good washer
