M6 Washers Black, 25pcs Flat Washers DIN9021, Jeboler 304 Stainless Steel Washers for Screws A2 V2A, Large Flat Repair Washers, Round Metal Washer Spacers for Bolts, Screws, Nuts（M6 x 18mm）

I like the black finish. Good rounded edges on the top side and no burrs on the bottom where they were stamped. The washers aren't precisely the sizes on the listing. The M8 ones I received were slightly undersized at 23.7mm diameter, 1.76mm thick and with an oversized 8.55mm hole. An 8.5mm drill bit drops straight through. The washers will be really useful around the house, workshop and garage. I used some shiny zinc plated ones on my motorcycle when fitting a rack. These black ones will be an excellent replacement for those.

These are premium quality stainless washers, but at a price!, maybe it's because they're black ( and you can get them overnight) rather than bright stainless. nice and thick with a wide diameter.

These washers have a black finish making them ideal for car trim fixings. They are described as stainless steel penny washers. Well they do seem to be stainless steel as they are not magnetic. The black finish does not look like paint, it is more like an anodised finish, but I’m not sure if stainless steel can be anodised? As for being penny washers , I would have to dispute this, penny washers are normally oversized on the outside diameter. These washers are closer to Standard M6 washers. That said if you only need standard sized washers these will be absolutely fine.

Good thick washers with a rust resistant black finish ideal for repair work very handy and a good price.

These M4 washers are made ok, accurate enough to do the job, and the coating is just about even enough, if not the best, possibly due to the slightly imperfect finishing in manufacture, but nothin thats effects performance really.They come in a little baggie, and at £5 for just 20 are pricey imo, so not great value, but otherwise they work ok.

25 pack of black penny washers, made of stainless steel, not much you can say about a washer except for they look to be very well made and are dimensionally accurate.

These are very good quality black M8 penny washers. Well made and nicely finished. Not a common product to find, just a bit on the expensive side, otherwise great.
