Wheels from a friend., noob question Options

[RallyeMonkey]

Here is my situation. My best friend gave me some gunmetal Arospeed RS-GT 17x7 5 with tires not positive on the tire size, as I am at work and can't walk out to the shed and look. He had them on a '02 Subaru Impreza WRX wagon. We put one on the front to see if it would fit and move ok and we managed to breakoff 2 studs ans strip the other 3. But I got my old wheel back on first. Then I went to Autozone and got some 12mm "tuner" lugs and I couldn't get them to thread right. I thought if they where the right size they would work. These are like the ones my friend had but they are 1.50 instead of 1.25. Is the different kind of threads, fine or coarse? Will these lugs work if I order them?



Sorry to waste anyone's time if this has been answered somewhere else, can never find what I am looking for when I search.

Lug nut size is the same, I just needed small diameter to fit in the wheel.

12 is the diameter 1.5 is the pitch. Higher # 1.5=.0590sae 1.25=.0492sae
.0492=20tpi (threads per inch) .0590= 17tpi
12=.4724 in between 7/16 and 1/2".
The outside diameters of the studs are the same the depth of thread,
and threads per inch are the difference.

Putting on bolts or nuts if you turn it counter clockwise
you should feel a little click, thats the start of the thread, stop,
turn clockwise if it doesnt go smooth right away stop turning
clock wise.

Thanks hopefully I will have better luck next time with that threading tip. And thanks for explaining the depth of thread and threads per inch. Gives me alot more confidence that I ordered the right lugs.
