## Customer Reviews

### ⭐⭐⭐⭐⭐ Great tool
*by D***A on December 22, 2024*

Item exactly as described. Worked great!

### ⭐⭐⭐⭐⭐ Good stainless carriage bolts, washers, and nuts
*by B***L on January 10, 2024*

Got these to replace steel bolts and washers for my snow blower rebuild. I didn't use the nuts, as I needed nylon lock nuts in this application. The finish on the hardware was good, and the bolt/nut threading was clean and smooth (no roughness or burrs). Overall I'm happy with this purchase.

### ⭐⭐⭐⭐⭐ shiny
*by B***L on April 29, 2025*

stainless steel fasteners for my application delivered to my housequickly, and at a fair price.a+
