Customer Reviews (4.8 / 5 · 5 reviews)

Sofia ★★★★★

The trivalent zinc coating is a nice upgrade—seems more consistent than standard zinc, and a thousand pieces should last me through many repairs. Worked perfectly to secure a stubborn mower blade bolt that kept vibrating loose each season.

Eva N. ★★★★★

I needed a bulk pack for a project and the trivalent zinc finish on these washers looks clean and resists corrosion well. The 1/4 inch size fit my bolts perfectly without any wobble.

Penelope ★★★★★

Our equipment sees heavy vibration and these #1 washers haven't let a single bolt back out since I switched. The trivalent zinc coating handles the humidity in our shop without any rust spotting. A full bag of 1000 will last me through several rebuilds.
