Inconel studs for turbo and head?????
Well I've been searching and searching with little results. I'm mainly looking for head to manifold inconel studs but haven't found many. Here are some below but I'm not sure the factory threaded lengths.
https://www.fensport.co.uk/products/...anifold-flange
Total Length: 40mm
Longest threaded section: 18mm
Unthreaded : 8.4mm
Shortest threaded section : 13mm
https://www.ecsexhaust.com.au/incone...-m8-x-1~131817
But worth mentioning is none I have found are in the states.

- OVERALL LENGTH - 40MM
- THREAD LENGTH FLANGE SIDE - 12MM
- SHANK + THREAD LENGTH TURBO SIDE - 28MM
But worth mentioning is none I have found are in the states.

I know ARP has a pack of (at least stainless steel) studs for our manifolds.
I personally have titanium studs on my exhaust side, hoping I don't regret that. Wasn't paying the most attention at that time when I ordered those.
ARP Stainless, probably what I should have gone with - https://ipgparts.com/products/arp-ex...series-engines

Worth noting is the ARP studs are 300 which is the same as 18-8. The same studs on McMaster are $2.61 each. Sure you will need to source nuts and washers but come on...

Titanium vs Stainless Steel: Shear Strength
Titanium vs Stainless Steel: Shear Strength
A material’s shear strength is its resistant properties against a shear load before the component fails in shear. The shear action occurs normally in a parallel direction to the direction of the force acting on a plane. Titanium shear stress is rated between 240 to 335 MPa depending on alloy properties while the stress of stainless steel is rated between 74.5 – 597 MPa. This shows that stainless steel is a perfect choice in situations where high resistance against shear load is required.
Also what I've come to find out is high tensile strength (10.9/12.9) vs medium (8.8) will lose their tensile strength with heat and also higher tensile strength is more brittle. Snapping vs 8.8 maybe bending. Just back on the topic of steel. Inconel is totally different though...

Re: Inconel studs for turbo and head?????
I don't see the point for inconel-treated manifold studs. Those don't reach anywhere near the temperatures that turbine exhaust wheels see. And I have a set of the ARP manifold studs. Nice stuff, but had to almost make a tool to reach the 12point heads of those things, especially when mounting the exhaust manifold.

Re: Inconel studs for turbo and head?????
What are you expecting to gain from inconel studs? The main purpose behind super alloys existing is because they are dimensionally stable up until their melting point. I would think as far as hardware goes, if you want to be fancy, titanium would be more than sufficient as it is pretty damn heat resistant. I’ve not had any problems with my stainless manifold hardware

And not just any alloy, it’s a super alloy. Yes that’s a real term given to any alloy that remains dimensionally stable up to its melting point. Inconel is of the nickel variety
im with you Dax, they may not be a total waste of money at the turbine housing

Re: Inconel studs for turbo and head?????
I had the same problem and needed to replace some of my exhaust studs and wasn't about to pay ARP $120 for a set. I ended up buying Volvo part number 953047, they're M8 x 45MM, and I believe are Inconel - but either way, are hardened heat treated. Works great and is way stronger than the OEM Honda studs.
