Customer Reviews (4.6 / 5 · 5 reviews)

Avery U. ★★★★★

I've been burned by cheaper washers rusting in coastal air, so the 316 stainless here is exactly what I needed. These feel solid and the 100-count pack means I'll have spares for years. Fit my #5 hardware perfectly without any slop.

Isabella W. ★★★★★

Exactly the right size for my #5 screws, and the 316 stainless gives me peace of mind they won't corrode in damp conditions. The .025" thickness is sturdy enough to spread the load without adding bulk. Came in a tidy 100-pack that'll last me years.

John Y. ★★★★★

These washers are noticeably thicker and more corrosion-resistant than the cheap zinc-plated ones I've used before. They fit perfectly under the bolts on my boat's deck hardware and should hold up well in the saltwater environment.
