320 Pcs Copper Flat Washers Assortment Kit Metric Sealing Washers M5 M6 M8 M10 M12 M14 M16 M20（12 Sizes）

Nice useful assortment.

I got tired of going to town and paying a lot for two washers.

just what I was looking for. I do oil changed on an assortment of different cars. No more trips to autoparts stores for crush washers

320 pieces of copper washer! Anything you need a copper washer for can now be found in your handy copper washer kit! I've used some for hydraulic applications, and engine parts. At least I know now I've got my trusty copper washers kit to save me from copper washer gloom and pesky visits to town for parts. Thanks Rustark!

I used just three crush washers for the diesel injectors. From the dealer , one would have cost more than this assortment. These are very slightly thicker than the OEM part- good. No leaks !

This kit provided me with exactly what I needed

The compartment box that it came in uses those variable dividers that would break loose and did indeed break loose.All of the different sized washers in the same row where the divider broke loose are now mixed up, I'm now forced to have to sort them out, which was the reason why I bought it in the first place was that I thought it would be sorted out neatly in a compartment box.Can't give it a 1-star since I did get the compartment box, but the washers are mixed up so have to take out two stars.DON'T USE VARIABLE compartment box/bins. That style is garbage, it's just a way for the manufacturer to do a "one design to do-all but does not do anyone of it properly" universal design we see everywhere these days.

Let's get straight to the point: these are NOT as high quality as the OEM washers that came with your European or Japanese machine. But they are of enough quality to perform the job (namely, provide sealing) at a fraction of the cost. What's more important, the assortment provides sizes that may be simply very hard to get from the OEM. I am overall satisfied with the purchase.
