What are the dimensions of a Renix 4.0 TPS bolt and IAC bolt?

Okay so my search hasn't exactly been the most fruitful of the following question. 

 

What are the dimensions of a Renix 4.0 TPS bolt and IAC bolt? I wanted to replace the bolts because I lost one, the other TPC bolt started stripping at the torx head, and the IAC bolts somehow have a triangular shape to the shaft. On a whim yesterday, I took the TPS bolt to the hardware store, and it seemed to match with an M5, but the M5s that I took home seem too big. Today I returned and noticed that the TPS bolt will thread into both the M5 and the 10-32 gauges. But when I compare the bolt to what they have, it seems the threads don't sawtooth together with the 10-32 bolts. Or maybe it was 8-32, heck I dunno, I've got so many numbers already to memorize...

 

The IAC looks to have a larger diameter shaft.

 

'89 4.0 Renix, by the way.

The triangle threads are supposed to be there. It is a "lock bolt". Like a lock nut, but for bolts usually into blind holes.

I guess that makes sense because I had no clue how they would have gotten that way.

I've visited two very good hardware stores and the one bolt that I have is a unicorn to them. The thread pitch is not 24 or 32. M5 80 is a bust, both 8 and 10-24/32 are a bust.

Those TPS screws are a super goofy size, like 5.5mm or something. You're not gonna have any luck finding them aftermarket. Talk to Jeff Leigh jeff@strokedjeep.com he can tell you the exact size and may have some, I sent him a bunch of them when he bored my renix TB. Only place I've been able to find those screws are the junkyard.

I continued my search for the query and after nearly an hour looking online, through some miracle I may have come up on the answer incidentally. I don't know yet, but apparently the Renix TPS screws are 8-36x1". 

 

I looked. Ain't not a one of the damn hardware stores within fifty of me have ever carried a 36 thread bolt before! 

 

Luckily, I have learned that McMaster-Carr has these size bolts. I'm going to order some tonight, and if they fit, I'll be posting on here with a link an everything because I doubt I'll be the last cat on the block to ask this question.

Okay folks, here's the skinny!!!

 

For those curious or in search of the answer: My '89 4.0 TPS required (x2) 8-36x1" bolts. It is my understanding that this is the standard with Renix Jeeps.

 

Yes, McMaster-Carr does indeed stock what you will need, however, I ordered from eBay because I didn't want to create another account at this time.
