Customer Reviews (4.8 / 5 · 5 reviews)

Benjamin Y. ★★★★★

Had a loose bolt issue on my trailer gate that kept coming back after every trip; these washers finally stopped it dead. The zinc coating looks clean and should last well even with some road moisture. Exactly the bite I needed for a secure hold under constant vibration.

Miles ★★★★★

Installed a set of these on a small engine mount and the vibration hasn't budged them at all. The 5000-count bag is perfect for keeping spares on hand for future projects.

Christopher S. ★★★★★

The zinc coating feels smooth and consistent across all the washers I've checked so far, which gives me confidence in their corrosion resistance. I've been using them on a small vibrating assembly for a few weeks, and not a single fastener has loosened up.
