Hi all, I recently invested in some new wheels but the problem I am facing is that my current lug nuts are too big and don't allow me to fit my socket in there. So I am being forced to buy new lug nuts either floating or extended ones however I have been unable to find a set answer to the thread size. Some say its 1/2" but does that translate directly into a 1.25 (m12 x 1.25)? If so would these wheel nuts be okay? http://www.gktech.com/index.php/open-en ... 0-727.html

You need 1/2 inch 20 tpi from memory.
Metric does not cross over.
Somebody correct me if im'e wrong.

^^^^ This dude is right...

1/2" is bigger and stronger than 12mm... Hence Holden speedway cars push the 12mm studs out and fit Ford 1/2" studs (not bigger by much, but bigger is bigger)...

I don't know the TPI (threads per inch)... But it's called 1/2" UNF... Which is "something something fine"... There is a 1/2" UNC too which is a***... They look nothing like each other... I doubt you'll buy a 1/2 UNC wheel nut... UNF is better because the pitch isn't so steep they're less likely to undo... All your seatbelt stuff is 1/2UNF too for the same reason...

1/2" is a bit hard to find as most tuner stuff is out of China or Japan and they're both completely metric... Ford is from America and hence why to this day 1/2UNF is still a semi common wheel stud size...

Cheers,
Tim

Imperial and metric threads are not, NOT, interchangable.

The problem is not that your wheel nuts are to big but that the recesses in the wheels are too small.

I found this when I purchased new wheels a while back, but mine were supplied with new wheel nuts, old 21mm socket, new 19mm socket. I didn't like the way the nuts sat deep in the wheel so I tried fitting my old nuts and found that my deep socket that I usually used wouldn't fit. Grabbed a 21mm spark plug socket and all good.

Try using a thinner wall socket.

1/2" UNF wheel nuts are everywhere. Every wheel shop sells them as does all the parts outlets.

Not all fords are 1/2 UNF i found that while looking for sum lock nuts for my new mags Ford Focus fit the M12 x 1.25 lock nuts so it may say Ford but this doesnt include Ford AU to BF/FG so keep that in mind
Ford AU up to FG uses the 1/2 UNFwheel nuts only

German ford so its going to use metric.
