Dual LP 30 lb tank hold down rod thread size

[PSU1981]

We have a 2015 27FB FC that I am trying to determine the thread size of the hold down rod for the propane tanks. I think it is 3/8” or 1/2” but not sure which one? The owners manual does not say.

Thanks,

Glenn

Use a 3/8, 7/16, and 1/2" nut and see which one fits.

Well that makes sense - thanks!!

The hex nut size does not correspond with the thread size, i.e. 3/8 thread=9/16 hex wrench.
It appears to be 1/2 x 13 course thread, if you have the wing nut, that will help you at the hardware store.

Thanks!!

The wrench used does not correspond to the thread size. The size of a nut is based on the inner diameter not the outer diameter. A 3/8" nut might use a 7/16" or a 1/2" wrench. Just go to Home Depot or Lowes and buy one of each size and see what fits.

+1 for bringing the wingnut into hardware store to size it

However, check it against several bolts in different bins. People don’t always return items into the bin they took them out of. I’ve made many trips back to the store after discovering that all of the items coming from a bin we’re not the same

Me, I use my tap & die set when in doubt

I replaced my original propane tank rods on both trailers with ½" x 13 thread 36" long 304 stainless steel rods that won't rust. Also used stainless nuts and washers doing the replacement process. Got them from Grainger supply.

I used a stainless steel rod as well, mine is bent into a "candy cane" U at the bottom.

It's too long to go out the bottom without jacking up the trailer.
