Evelyn F. ★★★★★

Bought these for a drawer slide repair and they fit perfectly on the 5/16 bolts. The steel feels solid enough that I don't worry about them bending out of shape, and 700 in a pack means I've got plenty left for future projects.

Isabella ★★★★★

The silver finish on these lock washers is clean and consistent across the whole package, making them easy to grab quickly. I used about half of them securing a mower deck, and they held fast under the vibration. Exactly the bulk pack I needed for shop jobs.

Julian ★★★★★

I grabbed these for a few small projects where vibration is an issue, and the steel feels solid. The silver finish is consistent across the whole package, which is a nice touch. No stripped edges or weak spots at all.
