    • Nice flat washers, very good value
ID and OD are nice and round, as you would expect. Thickness is appropriate, thick enough to do their job. Edges are not sharp, surface is bright without any staining. Better value than the big box stores, these are a very good value.

    • Thin-Not .35" thick as description claimed...0.0625" (1/16") at most.
The washers are round and have steel content. (magnet attraction) These work as 1/2" i.d. 1" o.d. .0625" thick steel washers. Do not buy if you are looking for a thick washer because of the description given. Not usable for my project. Kept as a standard 1/2" steel washer.
