Amelia T. ★★★★★

The surface finish is smooth and uniform across all 100 pieces, which made them easy to stack and feed onto bolts without any snagging. I've used cheaper zinc ones before and these 316s feel noticeably more substantial under the wrench.

Joseph ★★★★★

I needed a full 100-pack for a deck repair job, and these 316 stainless washers fit perfectly on the 3/8 bolts without any wobble. They feel solid and corrosion-resistant right out of the bag—exactly what I hoped for.

Joshua ★★★★★

The salt air around here eats cheaper washers in a season, but these 316s look brand new after six months on the boat trailer. They’re thicker than the usual pack too, so they really spread the load without bending.
