A number of outfits including Lawson fasteners made/make lug studs. https://www.lawsonproducts.com/Wheel-Bolts-carlight-truck/BrakeWheel/Automotive/AT110050.lpc
When changed the pattern on a Pontiac axle to a Chevrolet I went thru the Dorman drawers at a parts store and found the knurl size as close to the 1/2" threads as I could. I drilled holes 1/2" and pulled then new studs in using a used 6206 ball bearing, washer, and lug nut upside down, and a breaker bar. Haven't failed yet and that was 30 yrs ago.
I used to do them with some greased up flat washers stacked under the nut when I was doing brakes every day and ran into broken or stripped studs on a regular basis. A bit of hunting shows that NAPA calls them wheel bolts. https://www.napaonline.com/en/search?text=Wheel+bolt+&referer=semantic&se=1 O'Reilly's calls them wheel lug studs. This should be the full list as I cleared the vehicle application. https://www.oreillyauto.com/shop/b/...-lug-stud-12672/f9d310318873?q=wheel+lug+stud When you look at 1/2 inch you have 91 choices to sort though. https://www.oreillyauto.com/shop/b/...3?q=wheel+lug+stud&prodAttr_10648=1/2-20+Inch
I don remember the numbers but I used wheel studs for a 56 F100 to press into the 40 hubs on my 39 sedan. I just had to grind a flat spot in the head of the stud so it would fit on the back side of the hub where the stock ones were flat too.
