Customer Reviews (4.8 / 5 · 5 reviews)

Robert ★★★★★

The .040" thickness is exactly what I needed for a snug fit under my #8 screws, and the 18/8 stainless finish looks clean on my outdoor project. A thousand in one bag means I won't run out for years, which is honestly the best part.

Miles ★★★★★

Was pleasantly surprised by the thickness of these washers—.040" feels sturdy enough for furniture assembly without bending. The 18/8 stainless steel finish looks clean and resists rust well so far.

Henry ★★★★★

The .040" thickness feels just right—sturdy enough to protect the wood without adding bulk under the screw head. I’ve already used a few hundred on a metal shelf project and they’ve held up perfectly, no rust or warping.
