Customer Reviews (5.0 / 5 · 5 reviews)

Thomas ★★★★★

Exactly the right thickness at .031" to sit flush without adding too much stack height under a bolt head. The zinc plating is consistent across all 1000 pieces, and I didn't have to fish out a single bent or flawed washer from the bag.

Mia Y. ★★★★★

The zinc plating gives these a smooth, uniform finish that doesn't flake off when I'm torquing things down, and the .031" thickness sits flush without any wobble. Spent an afternoon sorting a few hundred for a frame project and didn't find a single warped or burred piece in the whole batch.

Ella W. ★★★★★

The 1000-count is perfect for restocking my hardware drawer, and the 0.031-inch thickness feels sturdy under a bolt. They distribute pressure evenly without deforming on softer materials.
