I think the threads on the base of my GE for the thumb screw are stripped, it won't go in at all and the thumb screw itself looks ok. Whats the best way to fix this? Its a cast iron base

Run a tap into the base hole that is messed up. I don't know the thread size or TPI but someone here may. You'll need to know before you tap the hole. Check the thumbscrew in another of your fans to make sure it's ok. A photo of the screw and hole location may be helpful.

Thanks Steve. If I were to take the screw to my local hardware store would they be able to tell me the the thread size is? I'll take a pic of both things and post it too.

Problem Fixed Guys! :D Turns out there was something on the threads in the base. If someone could please still tell me what the thread size is though for the future I'd appriecate it!

If you can find a nut that fits your thumbscrew and a bolt that that nut fits also you can confirm. However, in the early days and with lots of older fans, there were not always standard thread sizes so a fan might have something that you can't find a modern replacement for.

Adam,
I checked one of my brass bell oscillator thumbscrews at the top of the base and it's an oddball. Maybe around 30 TPI but my thread gauge doesn't have that number. Anyway, you'd probably have to have a special tap to clean the threads so it's good that your problem is fixed.

GE used a lot of odd-ball threads.  You can't just go to the local hardware store for most of their threaded stuff.

Yes it is, Steve. I just did alot of work to the base to restore it to its current condition, it would suck if I couldn't have fixed my problem

Best and usually only place to find a replacement is from a 'donor' fan. I even tried going to a big time professional bolt, nut and screw supply company  and that was their solution to the dilemma.
