## Customer Reviews

### ⭐⭐⭐⭐⭐ EXCELLENT ASSORTMENT!!
*by V***0 on May 24, 2020*

I did tons of looking and this is the best assortment of Grade 5 nuts and bolts for the money. The included case is plenty sturdy for storing them, however, I always use my own organizers. You cannot go wrong with this purchase and shipping was pretty darn fast.

### ⭐⭐⭐⭐⭐ Decent set. Good hardware! So handy to have these sizes on hand.
*by J***N on August 3, 2019*

Good quality hardware. I didn't use the included case. It seems ok as long as you keep it in a drawer of your workbench and not rattling around the bed of your pickup truck.
