Customer Reviews (4.8 / 5 · 5 reviews)

Charlotte ★★★★★

The 300-pack gives me plenty for multiple projects, and the .030" thickness is just right for preventing scratches without adding bulk. These brass washers distribute the load perfectly on my small bolt connections.

Lucy T. ★★★★★

Picked up a pack of these brass washers for a small electronics project and the uniformity is spot on—every single one fits my #6 screws perfectly. The 300 count means I won't have to reorder for a while, which is great for a few builds.

Matthew L. ★★★★★

The .030" thickness gives these washers just enough bite under a fastener without adding bulk—perfect for load distribution on my workbench projects. All 300 arrived clean, no burrs or rough edges, and the brass finish looks sharp against the hardware I paired them with.
