## Customer Reviews

### ⭐⭐⭐⭐⭐ Time saver
*by B***B on May 25, 2020*

Good luck finding these at ACE hardware. Also they're small diameter so they work with recessed socket head cap screws commonly found on industrial machines.

### ⭐⭐⭐⭐⭐ Wonderful SS Lock Washer.
*by L***L on June 29, 2020*

Added security against bolts coming loose. Great fit and great product at a great price.
