Customer Reviews (4.6 / 5 · 5 reviews)

Samuel U. ★★★★★

Finally, washers that actually resist rust when I use them outside on the deck. The 18/8 stainless finish has held up through a couple of rainy weeks without a single speck of corrosion, and at .125" thick they feel substantial when tightening down.

Julian K. ★★★★★

I needed heavy-duty washers for a boat trailer project, and these stainless ones handle saltwater without rusting. The 18/8 steel feels solid and precisely cut, no burrs or sharp edges. Perfect for distributing load under carriage bolts.

Abigail R. ★★★★★

The .125" thickness gives these real heft—they don’t bend or flex when I torque down on them. The 18/8 stainless finish is clean and uniform across all 100, and the price per piece is hard to beat for this quality.
