Switched from using a torque wrench on every bolt to just going by feel on interior panels

Used to torque every screw on cabin panels since I started 7 years ago at a regional airline in Dallas, but after getting burned by a digital torque wrench that was 30 ft-lbs off, now I just hand tighten and check with a wiggle test, has anyone else dropped the torque specs for interior work?

That digital wrench being 30 ft-lbs off is exactly why I stopped trusting them for anything but engine work. On interior panels you're really just fighting against the plastic cracking or the screw stripping out, so feel and a wiggle test makes way more sense to me. Have you noticed any differences in rattles or loose panels between the two methods over time?

Thought about this a lot after messing with some older cars. The real difference shows up when you get into cars with those little metal clips that hold the panels on instead of screws. Torque wrenches don't help there at all, you're just pushing the clip into the hole and hoping it grabs. But if you use a torque wrench on those, you'll snap the clip or deform the panel around it. On the other hand, I've noticed that hand tightening can leave some clips barely seated if you're rushing, and that's where the rattles come from a week later. The trick I've found is using a 1/4 inch drive ratchet with your fingers on the head, just enough to feel the clip click into place, then a quick gentle tug to make sure. That method has held up better for me than either full torque or just guessing with a screwdriver.
