I have new axles going in my car and I need to buy some 7/16 press in studs. In summit they have alot them but the knurl dia differ. How can i figure out which ones to buy ?

 

Safest way is to measure the holes in the axle with a dial caliper. Knurled dimentions will be slightly larger than the hole for a proper press fit.

 

Sounds easy enough thanks.

 

the stock studs are 12mm 1.5, I assume you know that, but just making sure

 

My arent stock. I have dual pattern axles. 7/16 press in and 1/2 screw in.

 

ok, thats cool, just making sure

 

Take an axle to the auto parts store and get the right studs. Forget Summit and get them local. You probably need a 610-186 stud. which is the 7/16 stud that was used in the early Camaros and Chevelles.

 

Do you know the original knurl size of the studs that came out? If so, get some new ones that are slightly larger for a tight fit. One thing I don't understand is....why 7/16 studs? I would use 1/2" 7/16 is so tiny (all C2 and C3 vettes have them and I upgraded to 1/2" because they are that iffy)

 

These are bran new axles.7/16 is close to the stock 12mm studs and they have been holding fine. I dont need 1/2 studs I think its overkill for my car i'm only put down 400hp at the crank and plus I dont think they would fit my cragar ss/t rims anyway.

 

Cragar rims have what, lugs with a .685 shank size? You can simply get 1/2-20 lug nuts for that shank size
