Several of you asked me to post my findings on the Acura TL wheel studs. I figured I'd start a new topic so someone could search more accurately.

Fact #1 - The 1992-1995 Civic wheel stud knurl diameter is .480", and the entire stud length is 1.674" long.

Fact #2 - The 1996-1998 Acura TL-3.2 REAR stud knurl diameter is .480", and the entire stud length is 2.079" long.

Holding the TL stud up to the H&R stud (the ones that come with the 5mm spacer kit for the Civic) currently welded into my hub, they look to be exactally the same length. Now, the TL studs are more expensive at about $4 each from the dealer. However, it appears that they can be had for slightly over $3 from acuraautomotiveparts.net as Tyson will attest to.

Not that there's anything wrong with the H&R studs since they seem to work for everyone but me, but looking at the H&R knurl, it's got about 1/2 the "teeth" as the OE Honda/Acura ones do, so it doesn't have quite the "grab" into the hub bore as the OE bits. I ended up welding my H&R studs into the hub since they were loose, so they'll most likely work just fine now.

This is a side-by-side picture of the factory Civic stud next to the TL-3.2 rear stud. If you order these, remember to specify the TL-3.2 series, and the REAR studs. Keep in mind that this is simply another option for those looking for a longer wheel stud with a OE fit. Please feel free to add useful information to this thread.


A few days before my "issue" with the H&R studs, I ordered a full set of 57mm H&R studs. I'll probably still use them, but I'll defenately weld them in.

thanks for the info. Btw, that comes out to 10mm extra, not bad.

So while we're on the topic, which ARP studs are the proper ones to use?

I've seen two different part numbers used successfully.

 

None to my knowledge. The ARP knurl is 1/2" diameter and requires drilling of the Honda hub. If you forced it in, that's bad mu-ju.

 

now I need some wheels and lugs to have a reason to buy those>

 

I have 10 H&R wheelstuds that were shipped with my 5mm spacers that I purchased for my ITR.

Does this mean I can use these wheelstuds on my Civic?

 

I can't "confirm" that the ITR studs are the same. Maybe someone else knows.

 

Do you know if the TL stud will fit a 99-00 Si hub?

 

Both the civic and Integra studs have the same sized knurl. The only thing that is different is the length of the stud. Obviously a longer stud can be used in a broader range of honda products. The TL stud John got can be used in a 99-00 Si hub as well.

 

one more bit of info that I and Tyson can attest to, use anti-seize. This is more for the open track & road race folks to have to deal with the higher heats that transferes to the stud & lugnut.

Thanks for the info John!

 

I'll bet the "new" 3.5 TL studs are in fact the same dimension as the 86-89 Teg rear studs that I posted info on about 2 years ago.

EDIT: I found my extra 86-89 stud (bought nine JIC) and it has a 1.878 OAL.

BTW make sure you have some open-ended lugnuts packed away with your spare tire. The factory chrome nuts will bottom out on the longer studs and not hold the wheel in place.

give the man a bone, same part number for integra and TL. i vaguely remember you mentioning awhile ago.

i do believe Moroso makes a set to the same specs
its a late model GM bolt
i will have to look into the part number again
found it
46150 Wheel Studs—7/16"-20 x 2-7/8" Press-in, .480" dia. knurl and quick start dog end, fits most late GM drum brake applications. Standard hole size: .472" to .479"

Just have to use "SAE" lugs. Something I don't wanna have to fight. I already have enough different lugnuts.

 

Problem is I have seen lots of Honda lugs snap. I hope the aftermarket ones are tougher.

 

So are the TL lugs the same ridiculous $5/pop as the 00 Si lugs??

 

I think John said they were $4 each.

 

Wheel studs are overrated. Double-sided tape owns!

- Sorry, very tired, goodnight.

 

Jeez, you got 'em for "only" $5? Parts direct from the dealers around here are somewhat high.

 

Lugs, not studs. I know its late....

 

I have a set of H&Rs that I haven't yet installed. What problems did you have with them? They were loose?

 

Yes. The H&R knurls didn't grab the hub like the OE ones. Others don't seem to have the same problem I had. Go figure.

 

I went through this a few years ago. I went to my local car supply shop and sorted through the bins until I found what looks exactly like the TL lug pictured. Everything was identical to the Integra GSR lug I wanted to replace except the length of thread. I think I payed just under $2 each.

Somewhere on this board (or its predecessor) I posted the part number and manufacturer, but I'm just guessing the search won't work (again) and I don't have the box anymore.

 

This is just a follow up in an effort to keep all the information in one place. Sorry if the horse is already dead.

This is a picture of my new 57mm H&R studs (the ones I ordered before I had the problem) in comparison to the TL and the Civic stud. You can see the knurl on the H&R stud is quite a bit shorter, and the "head" of the stud is thicker. Imagine each stud seated flush into the hub. The H&R stud looks to have less "grab" than the other two, therefore, may be the reason mine were loose and required welding.

Does anyone see any reason why tack-welding wheel studs would be a bad thing? Besides the obvious replacing problem.

 

I cant think of a reason why i would be bad...other than replacement like you mentioned. It may actually be better because of the added material from the welding....better heat dissipation. Heat dissipation dosent matter if you arent taking the wheels off while the car is hot, though.
