M10 x 20mm OD Flat Washer, 18-8 (304) Stainless Steel Washers Flat, 50PCS

Good steel washers. As good as any other washers I have used. delivered in a heavy duty zip lock bag.

These are exactly as described. They have worked very well in my projects. I am very satisfied with the value and performance of the product.

No complaints.

good deal

They are sturdy and rustproof

These are thinner than the SS washers I would buy at the local home improvement store, but they are MUCH less expensive, so I suppose it evens out. It will be fine for many purposes. Some 1-star reviews claimed that they are not SS because they are magnetic. I haven't tried that, but ferritic stainless steel is definitely magnetic due to the presence of ferrite. I don't know the composition of these washers, but magnetism is not a good test. Leave it out in the rain and see if it rusts. That is the better test. If these rust, I'll report back.

Bought it for my table. I have used it for free months and everything goes good.

These look fantastic with 5/16” bolts. They’re a touch smaller than 5/16” flat washers. M8 is great. Quality product, no issues

einwandfreie Qualität, gute Verarbeitung, nix zu meckern

Statt 21,0 mm nur 19,5 mm Durchmesser. Hatte mir eigentlich was dabei gedacht. Nun nicht verwendbar. (Edelschrott).

Die gelieferte Ware passt nicht zu den Bildern. Und dann sind die Unterlegscheiben auch noch kleiner als angegeben. 11,7 Durchmesser, 6,4 Lochdurchmesser und 1,4 Dicke.
