Kevin ★★★★★

Pulled a dozen of these out for a kitchen cart assembly last weekend, and the 18-8 stainless is definitely corrosion resistant. They grip tight under the nut without slipping, which beats the cheap zinc ones I used before.

Lily Y. ★★★★★

Installed these on a motorcycle bracket that kept shaking loose, and the 18-8 stainless steel held up perfectly through a week of rain without any rust. Haven't had to retighten a single bolt since.

Claire ★★★★★

The teeth on these M8 washers really bite into the bolt head and surface, so I’m confident they’ll hold under vibration. I ordered the 400-pack expecting decent quality, but the stainless steel finish is noticeably clean and consistent across every piece.
