wheel nuts

[CamperStu]

i have a 2104 Jayco ultralight X19-H
i am missing a wheel nut any idea what size or type?
i checked the manual for the dexter axle /Sendel rim/ user guide ,no mention of wheel nut .. my local hardware store has a White Night type of nut but they have 7 different variations any idea where i can get the information for the replacement wheel nut size and type ?
there is a 1/2 marking on the nut not sure what it means could be the thread .. i need the cone shape size thread etc...
thanks

Take one off and go to a tire store. Odds are they can find one that fits.

Thanks for the quick response ;i can get anything to fit but if it is the wrong cone size shape i may start loosing other nuts..
not sure why something so important has no documentation..

You should be able to get them at any auto parts store, tire store, honestly I wouldn’t expect them to be listed in the owner’s manual, I have never seen lug nuts listed on any automotive owner’s manual either, easily accessible part to find locally in any city

Make sure you get the right cone shape for your rim. When I replaced my factory tires with Goodyear Endurance last year, I got a new rim with a spare so I effectively had 2 spares... After having to change a tire because of a leaky valve, I determined (after a 30 minute drive home) that the new rim didn't have the same cone shape (it was flat), it totally messed up my lug nuts and I had to buy a new set. I ended up having the Endurance put on the original spare rim and chucked the "new" rim, at it had some big groves in it.

While the trailer was parked in my driveway I took off one of the lug nuts and brought it into Canadian Tire and got a new set with the correct shape and thread size.

If it is any help, my 2016 x213 with factory aluminum rims (and the steel spare) takes these:
