Undercover bolt torque?

Undercover bolt torque?
Hi Everyone,
Does anyone know the correct torque for the bolts that hold the engine undercover in place? I've looked all around and searched through the FSM. Typically it will show the bolt torque on the diagram but as you can see it's not specified.

In the past I've just made them snug (I think professional mechanics would call it "half a grunt") and I may be a bit pedantic but, while I'm no he-man body builder I have over tightened nuts and bolts in the past which is why I tend to torque nearly everything these days. Better safe than strip the threads!
Thanks in advance!
Larry.

I'm just guessing the 40 in/lbs because a 1/4-20 fastener is about the same size and they are torqued to 48 in/lbs. Subtracted 20% for a fudge factory because I think the threadserts in the chassis are actually the weak point and thus I came up with 40 in/lbs. Haven't tested it on my vehicle yet though. I usually just hit them with an impact driver and feather the trigger and make it hammer for only 2-3 clicks which from my experience is about 1.5 ft/lbs per impact, I wouldn't really recommend that tool however unless it's something you use every day like I do. A safer alternative would be a battery drill with a clutch set on like.... 9 or so. Then they're all "torqued" the same, QUICKLY, without all the time spent with a ratchet.
