David E. ★★★★★

I'm always wary of washers that arrive with rough edges or burrs, but these M12 ones are perfectly finished and the 316 stainless steel feels genuinely solid. The load distribution on my trailer mount has been flawless, and they haven't shown a hint of corrosion after a month of rain.

Jacob ★★★★★

Installed these on a boat railing where salt spray is constant, and the 316 stainless is already holding up perfectly without a hint of rust. The load distribution under the bolt head feels solid and secure.

Alexander ★★★★☆

Bought these to keep deck screws from sinking into the wood, and the 316 stainless gives me peace of mind against rust in coastal weather. The 100-count pack means I’ve got plenty left over for future projects, though the edges could be slightly smoother out of the bag.
