evaporator stud part number help (i did something stupid...)

There are two studs (and nuts) that help secure the refrigerant (evaporator and accumulator) hoses to the flat housing of the evaporator. I couldn't see well last night and began removing them with 5mm sockets. One came out fine, but the other didn't. Under a better light, i see that they are E torx, and by my FSM, E7. Does anyone know the part number for these little jewels?

I can hit my local salvage yard tomorrow if they are expensive.


thanks-

Take the good one to ACE hardware or Lowes and match it up.

Thank you sir. The stud with the E7 drive on the end, I figured, is highly specialized so that Lowes wouldn't have a chance of carrying, but I will check.

Yeah def won't have the E7 on the end.
I'd get a bolt with that thread, cut the head off and then simply
screw it in by hand. (or slot it for a flat screwdriver).

Yeah, they most likely won't have stud with a Torx on the end. So like nab mentioned, just cut a bolt head off. Or, wouldn't be surprised if Lowes or HD have a small section of studs or even some "all-thread" rod. Just be sure to get something hardened and in stainless would be "very nice". See if there is a Fastenal store near you or even something like a Lawn Mower Repair shop for the Studs.


Edit - Napa, Advance, etc may even have them in the HELP section or exhaust section.

I just went through this recently. I replaced mine with bolts. New evaporator didn't have them.

M8x1.25 is the thread size.

I replaced with bolts. I forget the exact length but I measured the thickness of the hose and added 5mm.

Thanks for all the replies everyone. If I was a gearhead like days of old, I wouldn't have asked this.

If you use stainless steel, put anti-seize on them, or they will become one with the evaporator, which is aluminum. You will probably find them at the junk yard. It will cost you far less than chasing all over town for them.

Why did you pull them in the first place? When you find a stud, it is usually to make the installation easier by aligning the parts.
