Customer Reviews (4.8 / 5 · 5 reviews)

George X. ★★★★★

The black oxide finish makes these washers look clean and professional, and they grip the bolt tightly under vibration. Used a full bag on my lawn mower deck with zero loosening issues after a week.

Emily B. ★★★★★

Bought a full box for a small assembly project and I'm glad I did—the steel construction feels sturdy and the black oxide coating gives them a clean, uniform look. They bite into the fastener threads nicely, and at 2000 pieces per package, I won't need to reorder any time soon.

Grace ★★★★★

The black oxide finish is a nice extra, should help resist corrosion on my small engine projects. These #6 washers are exactly the right size for the bolts I’m using. Pack of 2000 means I won’t be running out anytime soon.
