Customer Reviews (4.8 / 5 · 5 reviews)

George ★★★★★

The exact 0.035" thickness was perfect for snugly seating a machine screw without wobbling, and the stainless finish hasn't shown a single speck of rust after a week in damp basement use.

Adam P. ★★★★★

Used these on a stainless steel railing project and the 18/8 material held up perfectly against the weather. The .035" thickness distributes load evenly without adding bulk, and all 100 pieces had clean edges with no burrs.

Ava K. ★★★★★

Finally found washers thin enough for the tight clearance on my motorcycle's caliper bolts, and these 0.035-inch thick stainless ones fit perfectly without binding. The corrosion resistance is exactly what I needed for outdoor gear.
