Matthew ★★★★★

The black oxide coating looks even and hasn't flaked off during handling, which is a relief for a bulk pack this size. At .040" thick, they feel sturdy enough to trust under a heavy bolt load without warping. Shipping five thousand of these in one box was the right call for my ongoing projects.

Samuel ★★★★★

I needed a massive pack of washers for a shop project, and these 5/8" x 7/8" black oxide ones are exactly what I was looking for. The .040" thickness feels just right for distributing load without being too bulky, and the finish hasn't shown any rust yet.

Charlotte V. ★★★★★

The black oxide finish on these washers held up perfectly during an outdoor assembly, no rust or discoloration after a day of rain. Each piece is consistently thick, so they stack evenly under my bolt heads without any wobble.
