Repair of broken studs in center caps?

How in the world do you get broken studs out of the center caps. I can't use heat without damaging the chrome and drilling it out is challenging since the holes are outboard of the center and it's hard to drill straight down...anyone have a cure?

I had to do this for my center caps too. I used a dremell to shave off the end and make it flat, then used a punch to make a little indentation. Then a drill to slowly make the holes. Its hard to keep it centered. It took a long time.


Or you can just pony up $100 for some nice ones on ebay. Not a bad deal (not my ad). I do see that a couple of these do have broken bolts now too.

Could you drill some rings out of plywood (hole saw) and layer them up to build a cradel to hold the caps up and then you would be able to use a drill press.

Drill Press only for that type of work.

I had one or two like that and set it up on a piece of plywood and then used another piece of wood to hold it down with a large wood clamp. Anything else and you are going to mare the finish of the chrome. Once it was held in place and centered on Centering Drill Bit, not a regular bit, we drilled to make a small pilot hole. Then used maybe a 3/32 drill bit to a certain depth. After drilling, we used a slightly larger reversed or lefthand drill bit to remove the broken bolt. Maybe 7/64 or 1/8 reverse drill. Came right out and I had several that were broken.
Next we used a 10-24 tap to clean the threads and then installed new stainless hardware, with anti-seize compound on the threads for future removal.
The new hardware was acquired from Totallystainless.com and the are OEM type Hex Flange Bolts of 10-24 x 5/8L. There are a couple of forum threads floating around about the screws that I provided the specs on.
