Hitch Ball Threads?

[WranglerX]

Brophy's replacement nuts are NF thread.

The TSC website has nuts.

Brophy doesn't specifically say replacement nuts only states it has NF nuts.... 1x14 is not NF....

And TSC does not state thread pitch....

NF is defined as 1x12tpi...

It is best to use a thread gauge or measure how many threads there are so you are sure.

Scroll down about half way and read the paragraph after the chart.

I wasn't really sure, but it turns out the one I have is a 3/4" diameter shank. Whatever definition you want to use, it threads very nicely into a 1/2" galvanized pipe coupling. Don't ask me what made me try that.

There you go, problem solved. Now you have a back up nut you can use. :drink:

Yeah, I don't think I would be trusting that, other than MAYBE for an empty trailer...!

Yeah, not exactly a lot of structural integrity there.

Well that cuts the possibilities down to 10 different thread pitches in 3/4".:laughing:

Standard fine thread....3/4-16, 1-14, 1 1/4-12. Lawn mower balls with internal thread...3/4-10

Most hardware stores only carry coarse thread nuts in sizes above 1/2", I have found. I prefer a grade 5 or better nut for hitch balls, although there is not much if any "pull out" force with a properly loaded and balanced trailer. In use, almost all the stress is against the side of the shank, in shear.
