Default Stud options (20mm spacers)

Regarding a 740 series;
I understand the Volvo wheel stud knurl is an odd-ball and I might be SOL but..

Has anyone identified a longer wheel stud that will work on the 740 hub from another manufacture that might be found at a local parts store?



Im going to run a 20mm spacer. The local availability is a sticking point because I was hoping to hit the road tomorrow. I've did some digging through the forums and found a few threads but i didnt see anything conclusive, though I might be using the wrong keywords.

I had to do the wheel stud project for an old rambler I put discs on and I remember finding a mfg'r chart comparing sizes, but for the life of me I cant dig that up again

I wouldn't care about changing lug nuts & running some goofy standard american size; primary concern is getting back on the road ASAP.

The 7/9 series utilizes 12x1.25mm thread pitch for the studs, which is a common stud. You can find these studs on many Subarus and other imports. If you can measure your current stud length, add 20mm to that and you will have a stud suitable to run. Autozone/O'Reilly's/Napa/CARQUEST should all be able to hook you up, probably gonna be $2/stud.

He wants to know the knurl diameter not the thread pitch.

240's have unusual shanks, larger than the threaded portion (heh, I found this out during my brake swap when I broke a 960 rotor), that might be what you are thinking about? The 700 series doesn't have this feature.

Forgive the live posting but it's a lot more fun than working

Volvo:
13.50mm knurl
.531" knurl diameter
47mm length

http://www.dormanproducts.com/p-2927...origin=keyword
Ford:
15.78mm knurl
.621" knurl diameter
73mm length

http://www.dormanproducts.com/p-2436...origin=keyword
Ford:
??? clip-head ???
.555" knurl diameter
2.31" length (~58.6")

http://www.dormanproducts.com/p-8122...origin=keyword
Vibe/Matrix
14.20mm knurl
.559" knurl diameter
55mm length (maybe too short??)

http://www.dormanproducts.com/p-3266...origin=keyword
Chevy:
????
.56" knurl diameter
2.37" length

Ok forget what I said, work is more interesting than all these knurls blending together

I was really hoping someone would chime in with "used studs from a ford/chevy/mazda/edsel/AMC/XXXXX and they fit fine." If i have to run different lug nut sizes for the time being, thats kosher by me.

I will be so sad if i have to go camping without her.

You're screwed by Volvo's proprietary knurl diameters just buy some ezaccessory or china-bay adapters.

In the long term, i am going to get a set of kaplhenke's for the rear...Im thinking the vibe/matrix option is do-able in the meantime.

Thoughts??

edit;
55mm under head length
-20mm spacer
-XXmm bolt circle depth??
OH GOD

I was never good at math and it shows

Following up on this;

-vibe/matrix studs are far too short for 20mm spacers
-buy kaplhenke's studs (& spacers) because a) they work b) hes a great dude who came through in a pinch
