## Questions & Answers

**Q: What is the size of the hex nut?**
A: 17mm, but an 11/16” fits loosely.

**Q: Can you put a 1/4"-20 nut on this thermowell?**
A: No, it’s 1/4” NPT threads. So plumbing fittings could work. Not standard screw threads. Look for 1/4” NPT parts.

## Customer Reviews

### ⭐ 1.0 out of 5 stars







  
  
    Prone to leaking
  

*by P***L on Reviewed in the United States on May 28, 2022*

The first one I bought was great and is still lasting to this day. Latter I bought two more but noticed the hex nut was smaller. I thought no big deal and went ahead and installed them on a couple pool boilers. They began leaking after two months and corrosion was forming. They claim 304 stainless steel but I think they are really  nickel coated. Mfg. from China was not helpful and went into denial. All they had to do was send me two replacements matching the original one I received and I would have been happy and written a good review.
