## Customer Reviews

### ⭐⭐⭐⭐⭐ These are my favorite grips.
*by R***S on January 13, 2025*

Not especially durable, no good grips last very long, but I like these a lot.

### ⭐⭐⭐⭐⭐ Great product, grest value, worked perfectly.
*by F***F on November 17, 2025*

Worked great, exactly what i needed (installing an aftermarket spoiler on my camaro that used this thread type but came with horrible mounting hardware, these bolts were a fantastic replacement), great value for the price.

### ⭐⭐⭐⭐⭐ Strong, Well-Made Hardware That Works Exactly as Expected
*by W***Y on March 15, 2026*

These worked exactly the way I needed them to. The machining and finish are clean, the threads are consistent, and every bolt in the pack was usable with no defects. The flange design is nice because it spreads the load and eliminates the need for a separate washer in many situations. The black oxide coating looks good and provides decent corrosion resistance for general shop and project use. The heads are well-formed and fit a socket cleanly without rounding or slipping. I’ve used several of them already and they tightened down smoothly with no binding. Overall, this is a solid pack of fasteners at a good value. If you need reliable bolts for projects, repairs, or general hardware stock, these are a good choice.
