Customer Reviews (4.4 / 5 · 5 reviews)

Penelope ★★★★★

The .030" thickness is perfect for my cabinet hardware installs — not too bulky, but still gives solid support under the screw heads. Nice to have a full box on hand for future projects.

Kevin ★★★★★

Exactly the right size for my electrical panel work, and the .030" thickness is perfect for distributing load without taking up too much space. The 18/8 stainless steel finish looks clean and feels solid.

Timothy Q. ★★★★☆

These washers fit my metric bolts perfectly, even though they're listed in standard sizes. The 18/8 stainless feels solid and hasn't shown any rust after a few weeks in a damp environment. Minor nitpick: the edges could be slightly smoother, but they work fine for general projects.
