I bought this set of tools at an auction today. as near as I can figure out it is used to drive out stuck bolts. There are five different thread sizes. a couple of them look like they have been pounded on pretty hard.

I thought they looked interesting so I bought them.

Are they tapered on the inside? It almost looks like a set of wheel lock and hub cap lock removal set from the 80's. You would hammer the closest size on to the smooth wheel lock or hub cap lock to remove them if you did not have the key. The first ones out were smooth on the inside and then they started making them with aggressive reverse threads on the inside.

I don't see any taper and the threads are not reversed.

They could be used to remove wheel studs on trucks. An example would be a 3/4 ton chevy pickup, you have to pound out the wheel studs to replace the brake rotor. The same is true for removing studs from axles, of course this is just a guess.

My thought also.

Hey Crash that's a older wheel stud installer set. I worked with a older mechanic that had a set of those in my teenage years.

If they're for wheel stud removal, whats the hex on the outside for?
I always used a nut (flat side up) run down flush with the stud to remove a stud that was to be replaced. If not for reuse, just hammer it out. One just lick works most times, if it messes up the threads, so what you not reusing them anyway. I used a couple of washer and a new nut to pull them in when replacing them (I use an impact wrench, just be sure to stop when it's pulled up
My guess would be something to set (install) some type dial pin that would only install to a certain depth, The hex still has me stumped.
