Amelia ★★★★★

The hardened construction is exactly what I needed for the bench top—it didn't deform or warp when I torqued it down. The black finish also looks clean against the steel, so it fits right in with the rest of my setup.

Henry ★★★★★

These black washers held up well under clamping pressure for a jig I built; the hardened steel didn't deform at all. Fit perfectly on the 3/8" bolts I had.

Ruby ★★★★★

Exactly what I needed for a tight spot on my lathe — the black finish gives it a clean look, and the hardened construction is a nice upgrade from ordinary hardware store washers.
