I recently obtained and then disassemble a Kink Co. BMX. It had a threadless headset. Unexpectedly, instead of having a star nut inside the fork's steer tube, the steer tube was internally threaded (threaded on the inside) and something screwed in. I lost that "something" and have no recollection of what it looked like. What am I working with here? I have never seen a fork like this. I obviously need to replace a part, but can't without any names whatsoever.

Welcome to bicycles.SE! It would help a lot if you posted a photo of the steer tube and noted any brand name or numbers written on it. – James Bradbury Mar 6 '13 at 15:58
A picture would be nice. You're probably just missing the preload bolt, but we can't tell for sure from the description. – cutrightjm Mar 12 '13 at 4:52

I think you're after one of these.

Does the same job as a top cap and star nut but has a hole you can run the front brake line down.

And they are called generically as "Pre-Load Bolt"? – user2525 Mar 6 '13 at 15:30
I believe so. Sticking "bmx preload bolt" in Google got a load of results.… – alex Mar 6 '13 at 15:33
How much does one differ from another? Do I need to be worried about hunting down the right size? The right brand? The right threading? Etc. – user2525 Mar 6 '13 at 15:39
Sorry, I don't know. I would assume they're pretty standard as long as you get the right diameter. – alex Mar 8 '13 at 1:15
