Reinstall AC - bolt torque
I put the AC unit back on the roof and tightened the bolts enough to make a decent seal and mush the gasket just a bit. Is there a torque spec for these bolts that I should be shooting for? I didn't...

New gasket is 1" thick and should be compressed about 1/2"....that is for new one.
The hold down bolts should be 'snug'.......so what is 'snug'?
Hand tighten then 1/4 turn with wrench.
Torque.....20 INCH Pounds (Notice: That's INCH Pounds not foot pounds). Very few folks have and know how to use an INCH torque wrench so that is why 'Just SNUG'
The amount of compression for new is correct and there is a torque value and not sure if the above benchmarks are correct, but they concepts are right.
For new I would use the compression amount and for older units torque to the specified value whatever that is and I'm assuming 20 INCH-LBS is correct.
