## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Over Priced.
  

*by E***E on Reviewed in the United States 🇺🇸 on June 20, 2022*

Appearance and functions well and it better because it's over priced.

### ⭐⭐⭐⭐⭐ 







  
  
    Great for ham radio antenna
  

*by T***9 on Reviewed in the United States 🇺🇸 on March 25, 2019*

I've been looking for larger 3/8-24 coupling nuts to replace some on a ham radio hamstick dipole mount. The ones that came with the mount were quite a bit shorter, and I didn't feel confident in their ability. These coupling nuts are much better - high quality and long enough to fit all the threads. These things are actually fairly hard to find; none of my loca hardware stores carried them (including the big orange and blue stores). In any case, if you're looking for these for ham radio, these ones will work a treat.

    I’m Nuts about these

Work as promised.
