Customer Reviews (4.6 / 5 · 5 reviews)

Stella Y. ★★★★★

Used a handful of these on a tractor hitch repair and they held tight without any rust forming after a week of rain. The black oxide finish looks clean and professional, plus the 2000-count pack means I won't run out for years.

William ★★★★★

Bought a full pack for rebuilding a trailer hitch and the consistent thickness across every washer made stacking them for the right load distribution effortless. No binding or burrs, which saved me from having to deburr each one.

Penelope J. ★★★★★

The black oxide finish on these is exactly what I needed for outdoor furniture bolts—no rust after a week of rain. The 2000 count means I’ve got plenty left for future projects, and they sit flat without wobbling under the fastener head.
