Eli ★★★★★

These washers are exactly .031" thick as listed, and the 316 stainless finish looks clean and uniform across all 800 pieces. They fit perfectly on #6 bolts for a small electronics enclosure I was building. No rust concerns with this material at all.

Matthew H. ★★★★★

I needed 316 stainless for a marine project and these .031" thick washers fit the bill perfectly. The package of 800 is great value and the material hardness seems just right for resisting corrosion.

Adam P. ★★★★★

A box of 800 washers for this price is a real bargain, and the 316 stainless steel feels quality. I used them for a marine project where corrosion resistance matters, and they fit perfectly.
