Lug nut size on 2014 26VFK

[txredfish]

I have a 2014 Flagstaff Superlite 26VFK with aluminum wheels.
Does anyone know the exact lug nut size? I tried 3/4" but it does not seem to be an exact fit. It appears to be a little smaller. There is some slop on the 3/4". I might be able to turn with 3/4" but I don't want to wear off the edges of the lug nuts. The is a sticker on the side of my trailer that says 100 lbs torgue using a star socket but does not give the size. I want to buy a socket that will fit just in case I need to change a tire on the road.
Thanks ...............

My mistake on the sticker on the side of trailer. It does not say star socket. It says star pattern for tightening the lugs but does not list socket size only the torque. Also, my trailer is 2015, not 2014 (typo). I went to dealer and he said 13/16 socket. I purchased 13/16 but did not fit (too large). I went back to dealer. The tech pulled out his socket set and went to a trailer like mine, tried his normal sockets and could not find one to fit. He was stumped so he went to is metric set and found a 19MM that fit. He seemed puzzled that the lug nut required a metric size of 19MM. He has not had this problem yet.
Did Forest River make a change on the Flagstaff to metric. Are the stud threads also metric? Owners manual says 1/2".

Most lug nuts since 1986 are metric. However, 19mm and 3/4in are virtually interchangeable. There is only a .005in difference.

Not sure what you are experiencing?
As was said, 3/4" SAE and 19 MM are usually pretty interchangeable when it comes to using a socket.

I always try to carry a six point socket for lug nuts. Even if it's not an exact fit, it won't round off the corners like a 12 point can.
