Lug Nut Size

Have 16" rims and thought they were 3/4 inch. Socket fits every nut except one. Wondering what happened to that one? Last time tires were off was when dealer replaced bearings greased it.

Could be that the chrome cover that is on the actual lug nut is slightly deformed by having the socket come off while taking off or installing. I just did that to one of mine.

Very confusing as the "manual" that came with camper on page 23 talks about torque wrench set at 120 and use a 7/8 or 13/16" socket. Purchased both of these and they are too big! I think the 3/4 is correct and what you said (Jcurtis934) is what has happened. Not blaming the dealer as I torque before each trip and last trip was in May. My camper has aluminum wheels and eight lugs.

What do you do if you have screwed one up???

If u can't get a lug nut of it goes to a tire shop.

In fact take a lugnut to a shop and find out what size they are and then order solid SS nuts that wont rust

Our original lug nuts that came on our rig were 1/2” thread solid chromed lug nuts that used a 7/8” socket. When we upgraded brakes to discs, the rotors have 9/16” studs and the solid chromed lug nuts use a 3/4” socket. Go figure. The best you can do is measure or just try several sockets until you find the one that works.

I always use a 6 point socket on lug nuts. The corners on my lug nuts are slightly rounded.

Good comment about using 6 point sockets! This morning looked at my four way lug wrench which has six point sockets. Notice it has 3/4, 13/16, 7/8 inch 19 MM sockets! Purchased a 3/4"six point socket to use with the torque wrench. The socket been using has multiple points. The problem nut has a little play in it so didn't try to test or tighten. Obviously not a mechanic! Already had an appointment at the dealer Monday so will add this to the list to be looked at! Thanks,

Normally, a 1/2"-20 thread lug nut will use a 13/16" socket. Unfortunately, "normally" isn't true for aluminum wheel chromed/SS nuts when some are 3/4". Either will work just fine since the tapered end is what holds the wheel in place. As long as that taper is correct, then you will be set to go. The lug nuts on our HC are 13/16" wrench size, the TV is 21mm but 13/16" will work. My '31 Ford street rod with Billet Specialties wheels, 1/2"-20 take a 3/4" socket. I don't want to get into lug nuts with a flat washer, no taper ...... but they exist as well.



I've not seen a 1/2-20 lug that uses a 7/8" wrench, but why not?

Just checked mine. 7/8 drive, 13/16 wont fit. 12-20 lug nut fits stud perfectly. Takes all kinds i guess.
