Hardware source M8X25X10 studs?

[sammm]

If you do use all-thread, put 2 nuts on the top to use for threading it in. That way you don't honk up the threads.

PS
I'd find the correct studs if it were me.

Yep so you don't bottom out the bolt in the head and to keep you from crushing the gasket if ya don't know what your doing.

I figured I'd just measure 10mm from the bottom to the top and loctite it in at that depth. That may not be ideal though, will call around.

Napa normally has the studs.

The Napa in Saginaw didn't even have exhaust manifold studs for me. I was floored - it's not exactly an uncommon thing for a car person to request, and ours are one of the more popular sizes. I'd highly doubt they have an odd size like he's looking for.

Point being, not all Napas are created equally

Ditto with my local Napa

Use the low strength loctite, I think it's the blue, so you can remove it if needed.

Any reason you couldn't just put a correct length bolt in?

Looks damn close! I didn't see a way to actually order it though or a matching nut.

[Fair!]

Ok here's what I need. Mcmaster has something close. 45mm overall with the 10mm side going into the head (which is correct) and the side that uses the nut at 22mm (which is close). Not sure if the 5mm overall length and 2mm nut side length difference will be a problem or not.

Dang, I literally have hundreds of those exact length/style studs in stock here... in M10 diameter. That's a special order part, for sure. McMaster Carr to the rescue! :)

You probably won't find them with any real plating, though. Black oxide is all you'll find, and it'll eventually rust just like the old one you pictured did. Not a big deal, though.

We order them in huge numbers in that common (crap) black oxide finish, them get them clear zinc plated, and then normalized (heat treating process). Total PITA, buts the only way to get these weird studs in a real finish.

You can but the studs hold the intake manifold so you can align it also the middle bolt is supposed to be a biatch to tighten.

Turns out the long end is too short. I did get a hold of a sales person at that company to see if they have the right part. This is turning to be a PITA. Checked Lowes, Autozone, O Riley's (had something close but no cigar), Elliots hardware in Plano, Fastenal, Grainger, Mcmaster and no luck so far.

Buy a longer stud, cut to size, clean up threads?

What have others done? I don't know what project you have going on (forget, and I'm too lazy to look back), but surely you're not the only one on the planet that has done what you're trying to do? (if so, props. and good luck)

I've actually gone down that route, and nothing is close enough. If the piece I found is long enough it's usually the unthreaded center section that makes it longer not the long threaded end. Most people that have done what I'm doing had these pieces as part of a kit. I'm starting to suspect they were specially machined for this kit only.

A good trick for cleaning up the threads, is to put a nut on it before you cut the stud.

Cut the stud, then clean up the end with a file, then remove the nut, the nut will clean up the threads when you remove it.

Ouch. All I can say is either contact the kit company or get ghetto and use some washers as spacers if you can (shouldn't be an issue if it's an intake manifold). Or get a bolt and a cheap open-ended wrench to grind down and make it work. I had to do that to get my FM manifold on and off - it was still tight, about 1/4 of a turn at a time, but infinitely better than trying to use a nonmodified wrench on one particular nut.

Cut the stud, then clean up the end with a file, then remove the nut, the nut will clean up the threads when you remove it.

I usually put the thread-chaser on the stud/bolt first, then back it off after I cut, but I've used a spare nut in a pinch too.

You may try calling McMaster-Carr. I have gotten screws from them that were not listed on the website by calling and asking.

Lemme guess - supercharger kit for the Elise?

If you get desperate Fastenal will make fasteners to your specifications. Doubt it would be TCB, though.

Are you replacing the one in the pic? If you are I think you could just run a die down it and clean up the treads. It does not look that bad. I am sure a new one would be better but if you can't find one.

Unfortunately that one is not mine, someone on the board was nice enough to take a pic of a spare they had. I picked up the phone and called the places I listed above and no one has one. I may have found someone that has some spares in Houston though so thinking I'm gonna go that route. Last resort is just to get a threaded rod and ghetto fab something. I'm not in a huge rush anyway.
