## Customer Reviews

### ⭐⭐⭐⭐⭐ Good price, Great quality
*by E***D on July 23, 2025*

Good price, Great quality

### ⭐⭐⭐⭐⭐ Rust proof bolts, very strong
*by N***S on May 10, 2025*

I used the bolts to secure a 40 pound battery with a 10 pound box for it by making them bold the beams together. that 50 pound load easily becomes almost double that weight once there are harsh bumps on the road (because of sudden gravity), those bolts aren't easily prone to bending, it's been time tested.

### ⭐⭐⭐⭐⭐ Worth buying.
*by S***8 on April 15, 2025*

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.
