Hannah L. ★★★★★

I needed a hundred black oxide washers for a marine project where rust resistance matters, and these fit perfectly under bolt heads without slipping. The consistent .063" thickness made them stack evenly, and the finish held up well during assembly.

Timothy ★★★★★

The thickness feels just right at .063", these washers sit perfectly flat under bolts and don't slide around during assembly. The black oxide coating gives them a clean, professional look that matches my other hardware.

Charlotte H. ★★★★★

I needed some sturdy washers for a hardware project and these fit perfectly—the 1/4 inch inner diameter matched my bolts exactly and the black oxide finish looks clean.
