actual size of lug nuts?

okay so I may just be dumb, but im confused. I had a flat on my 2014 jayflight while it was stored. took the tire off, np had it repaired. but when I went to put it back on the nuts seemed to want to either spin or not fit. they have the metal covers on them, one of which I cracked.
so I went to buy a new tire iron to keep just for the trailer. it says 1/2 inch on the nut, but I couldn't find a tire iron for that size?.. the salesman at Canadian tire said oh that's just the size of the cover....

im confused because I bought what he told me to and once nut I was able to tighten but the rest it wouldn't fit on?? btw he sold me 13/16 th ?

please help

thx

I suspect your Jayflight is similar to my 5th wheel in that the wheel lugs have a 1/2 " thread size and the lug nuts need a 13/16 " socket to spin off/on.

Nut size always refers to the size of the bolt or stud it attaches to - not the size of wrench or socket you would use on it. Same as bolt size refers to diameter of the threaded section of the bolt, not the head.

Just to agree and disagree with some of the above, The stud diameter would be 1/2", the tread pitch will be either 13 or 20(I think) depending if it is a coarse or fine thread stud. The socket size to fit it sounds like it will be 13/16th but the metric equivalent of 21mm will also work.(7/8th is equivalent to 22mm) If you use the wrong size socket(too loose) you will damage the chrome cap that covers the nuts.

I've found that a "deep" socket works much better than a standard socket or a tire iron. Also, don't forget to check your Jayco manual for the proper torque setting. You don't want to just "crank 'em down hard"!

Brownie: Thanks for your deep socket advice. I was about to buy a socket for my torque wrench and would have probably just bought a standard socket. Now, all I need to know is what size socket to buy. Seems from this thread that there are differing sizes of lug nuts. I have a 2015 23RB somewhere along the assembly line at the moment and cannot check for myself. Anyone within this forum know the proper size for certain?


Thanks...
