So, I went to install my new exhast studs yesterday. Coated them with anti-sieze, screwed them in as fas as I could with my fingers, then planned to simply double nut them to install them the rest of the way. I know it has been while (like a decade) since I have done this, but not exactly a lot to it right? Then why cant I keep both nuts from turning? (IMG:style_emoticons/default/051103-stupid4.gif)
Put on a nut. Check. Put on another nut. Check. Tighten them together. Check. REALLY tighten them together. Check. seat the exhaust stud. notsomuch.... what am I doing wrong? |

Top one spun toward the bottom one and vise versa. They need tension to bite the stud. edit: Oh, and you must have bought decent hardware. The low grade crap will work without turning them against each other due to the rough threads. |

Your not holding you mouth correctly. Ya got to get it really screwed up like this (IMG:style_emoticons/default/evilgrin.gif) . They are not tight enough together. Use a lock washer between or triple nut it. You are working from the top one, right? (IMG:style_emoticons/default/poke.gif)

And if you have anti-seize under , between the nuts , remove it , you don't need a lubricant in the double nut operation (IMG:style_emoticons/default/hissyfit.gif) . Installing the exhaust , those nuts could use some anti-seize , copper based if you got it.You are basically jamming one nut down on top of the other creating a bolt head to work with.
Good luck ....... Jack |

As previously stated use 2 wrenches and turn the nuts against each other. Will have no problems after that.

Bottom out the stud then back it off 1.5 turns, I think |
