### ⭐⭐⭐⭐⭐ Good Nuts !
*by P***N on May 30, 2025*

Great price, good quality, nice quantity. No shocker here, but way better to have more, than not enough. Cheaper by far from box stores, and a better grade SS.

### ⭐⭐⭐⭐⭐ Stainless steel, no corrosion, really nice product.
*by W***A on July 10, 2024*

OK, not the cheapest, but for outdoor application, these stainless nuts really hold up and resist corrosion I've been using these number of custom fabricated pieces and to date, never been disapointed.

### ⭐⭐⭐⭐⭐ My nuts worked great!
*by M***E on October 26, 2021*

I love m.y nuts. They worked great! They are very robust, and I'm sure will hold up for the long haul. They came in a sturdy sac which is nice because if you've ever had your hut sack split and your nuts went all over the floor it's a real pain. They were nice, shiny and clean too. They screwed really well even without lube. ...hard to go wrong with d.eeez nuts.
