Are these unobtanium?
I have a pair of Strange engineering axles with two stud patterns. 5 x 4.75 in 1/2 x 20 and 5 x 4.5 in 7/16 x 20. These have holes designed to screw studs into not press fit.

I called Dorman and ARP but struck out.
Why not "Strange" ?
Why not buy ARP 7/16x20 long press in studs, and cut off the knurled base? Or drill out your holes for the knurl, 0.005" smaller than the knurl for steel.

Use allen bolts screwed in from back side
+1 This is how I've always seen screw in wheel studs done.
Fully threaded bolt availability is a little limited, though. McMaster Carr lists an allen head fully threaded bolt that is 1 3/4" long. I haven't found anything longer than that. If you need something longer, you may need to think about drilling the axle for a press in stud as already suggested.
You want to be careful using regular bolts, especially on a street application for long term. Those ARP wheel studs have a tensile strength of 190,000psi while a Grade 8 bolt is closer to 150,000 and the Grade 7 all thread you'll find is 125,000. What did Dirty Harry say? Do you feel lucky?
Try your local Caterpillar dealer. Grade 8 hardware is the norm there.
.
Try a local google search for "Fastenal". Or "Bowman/Barnes" or even just "fasteners"....
You have another easy alternative. Drill out those smaller holes and tap them 1/2x20, or have your local machine shop do them if you don't feel good about it. Summit has a wide variety of screw in wheel studs, made for the service, in 1/2x20 thread.

if you can locate threaded rod that is grade 8 too then cut what you need
