brass exhaust nuts

[jct]

i know for oem nuts it's 30 ft lbs, but for brass no clue what to torque them too? they will be slathered in copper anti-seize

I would torque them to factory specs.

The anti-seize, if not factory OEM, can make that factory torque easier to hit and be too much, due to the lube factor of the anti-seize. The factory torque specs usually call for a lightly-lubed threads situation, rather than "dry" threads. That friction plus the stretching of the stud are what makes the final torque reading. Might need to use just enough anti-seize to cover the threads, rather than "slathered"? Then torque in segments until the final level is achieved.

Tight for no leak.

 

[jct]

since i left out some important infomation on the thread size (3/8-24) and torque of 212 in-lbs/18 ft-lbs

 

[jct]

tried to torque them down to 20ft-lbs striped the threads out of one nut

You will never get 20ftlbs on a antiseized brass nut.

Tight for no leaks.

Just don't use Stainless Steal boltz 'n nutz 'cuz it's ah one way trip. And you won't realize it 'til you try and remove them. Ever heard of the word Galling? The materiel of the threads will actually move as you tighten the nuts. Nylock nuts we all know about but they are forgiving. Stainless Steal nuts, NOT. Cutoff Wheel, Saws-all, Fire Wrench and they'll come off, Jer

Why are you using brass???

 

[jct]

So the studs won't break off when you try to remove the nuts

Also wanted to see what it would do when it did happen ._.

Good in theory, but...

It worked every time on our 210k mile Volvo 240 with already four sets of gaskets changed. Sometimes one stud came out with the nut, still intact.

I use a cocktail of copper based anti—seize and ultra hi-temp thread locker.
Works....

German specs... Gooden-tite.

Around here specs... tighten til' stripped, back off a 1/4 turn.

Just use the steel nuts and antiseize... You're making mountains out of mole hills again.
