Bolts appeared ok. We’ll see how they do in the salt water. Used the ones I didn’t lose due to the defective nuts!

Worth buying.

I bought these to replace all of the nuts and bolts that came with my smoker and tabletop grill because the included ones were cheap cast iron. I always replace the included bolts with stainless steel during initial assembly. It's a cheap but worthwhile investment. After almost a year, I haven't had any issues with them, so I'd say they're worth buying.

What can I say? They were the right size, no threading issues, and haven't broken yet. It seems a little harder to find fully threaded bolts at hardware stores nowadays, so I'm glad I found them here.
