I was unable to find anything like this on McMaster Carr.

I basically want an 1/8" pin that is 7/8" in length. The pin would have threads on top to secure itself after insertion.

Maybe this picture will help:



I need a way to secure that pin, I would love to just have the pin thread into the top of that part.

Or, while I have your attention, I am open to just about any idea for securing the pin.

Thanks,
Swami
