## Customer Reviews

### ⭐⭐⭐⭐⭐ Great assortment for projects and repairs
*by  on Reviewed in the United States July 16, 2026*

This is a very useful assortment of star lock washers. It includes a wide range of metric sizes, so I have several options available instead of needing to order each size separately. The washers feel sturdy, the teeth grip well, and the black finish gives them a clean, professional appearance. The quantity is excellent for the price, and this is a kit I’ll be keeping on hand for future repairs and projects.

### ⭐⭐⭐⭐⭐ These are handy to have around if you’re a DIY

These things are really handy when you need them. There’s a nice assortment of star lock washers included in this package and I think they’re a pretty good deal.

### ⭐⭐⭐⭐⭐ Internal Tooth Star Lockwasher
*by  on Reviewed in the United States April 15, 2026*

Nice to be able to get hardware like this when Harley Davidson makes them an obsolete part. Good variety and seem to work well. Fit perfectly on the part I had to replace on my 2020 Heritage Classic.
