Customer Reviews (4.6 / 5 · 5 reviews)

Emily G. ★★★★★

The zinc coating on these washers is smooth and uniform, not flaky like some cheaper packs I've tried. I needed a reliable lock for an engine mount and these have held tight through a week of heavy vibration with no loosening at all.

Carter I. ★★★★★

Used a handful of these on a vibrating conveyor and not a single bolt has backed off since. The zinc plating gave them a nice, clean look right out of the bag, too.

Charlotte ★★★★★

These zinc-plated washers held my workshop drill press together perfectly after it kept shaking bolts loose. The internal tooth design really grips well even on painted surfaces.
