## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great
*by P***. on July 6, 2025*

Excellent product great service

### ⭐⭐⭐⭐⭐ Good threads and holds up to the weather
*by K***N on November 6, 2024*

I used these to replace some failing fasteners holding the mirrors on my service truck. Installed cleanly, threads seem good, they are holding tight in the sheet metal panel and have not rusted after a few months in the weather. That's not the most strenuous test, but so far so good. Used a few on other miscellaneous projects too. The case is nice to keep things organized and will actually stay latched shut. You probably have experienced cheap little cases of fasteners that pop open at the worst times; sometimes the smallest things can be the biggest headaches. These rivnuts have been a good value and I would definitely buy them again.

### ⭐⭐⭐⭐⭐ Rivet nuts
*by J***N on April 18, 2025*

Very good quality
