Spinnakerblue89 Posted May 17 Share Posted May 17 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. Link to comment Share on other sites More sharing options...

It is a "lock bolt". Like a lock nut, but for bolts usually into blind holes. Link to comment Share on other sites More sharing options...

Spinnakerblue89 Posted May 19 Author Share Posted May 19 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. Link to comment Share on other sites More sharing options...
Airborne Janitor Posted May 19 Share Posted May 19 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. Link to comment Share on other sites More sharing options...
Spinnakerblue89 Posted May 19 Author Share Posted May 19 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.

Spinnakerblue89 Posted May 24 Author Share Posted May 24 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.
