Carter Q. ★★★★★

These washers are a perfect fit for my stainless steel deck hardware, and the 18/8 material resists corrosion like a champ. The package gives you plenty to work with, and they sit flush under the bolt heads without any slipping.

Thomas P. ★★★★★

I was replacing the corroded hardware on my trailer and these flat washers didn't skip a beat. The 18/8 stainless keeps them from rusting even after a week of rain, and the pack of 100 means I've got plenty left for future projects.

Hannah ★★★★★

The 18/8 stainless steel felt solid right out of the package—perfect for a deck repair where I needed corrosion resistance. Each washer has a clean, burr-free edge that sits flush against the surface. Definitely grabbing another pack for future projects.
