Customer Reviews (4.2 / 5 · 5 reviews)

Hannah H. ★★★★★

Bought these for a vibrating conveyor system and they’ve held tight through the first month of heavy use. The coating feels smooth and consistent across all 300 pieces.

Madison J. ★★★★★

These washers fit snugly over my 3/8 bolts and the zinc plating seems thick enough to resist rust in the damp shed. I used a full pack securing shelving brackets and haven't had a single one loosen up.

Jacob D. ★★★★★

Installed a batch on my mower deck last weekend and these split washers held tight even after bouncing across bumpy ground. The zinc plating on each piece looks uniform and felt sturdy in hand. Exactly what I needed for vibration-prone applications.
