Hot take: I stopped using torque wrenches on small panel screws and it saved me time

I know everyone says to torque every single screw to spec, but I work mostly on older Cessnas and Pipers where the panels have been on and off a hundred times. The threads are worn, the holes are stripped, and following the book values just leads to stripped fasteners and broken heads. About 6 months ago in my hangar in Wichita, I started using my calibrated feel instead of the torque wrench on any screw smaller than #8. I test them by feel and give them a gentle snug plus a quarter turn. I have not had a single screw back out or strip since I switched. The manuals are great for new aircraft, but on old birds with 30 years of maintenance history, you have to adapt. Has anyone else found that following the factory torque specs actually causes more problems than it solves on high time airframes?

Dude yes, same here. Got a 74 Cherokee that's had panels drilled and re-drilled more times than I can count. Started doing the exact same thing about a year ago, anything smaller than a #8 just gets a good snug feel. Broke three screws in one afternoon trying to follow the book on a wing root fairing, that was the last straw. Now I just do the gentle snug plus maybe an eighth turn and never look back. Those old Cessna cowl flaps are notorious for stripping if you even look at them with a torque driver. My stuff stays tight and nothing cracks, feels way better than fighting a stripped hole at 3pm on a Saturday.

Calibrated feel instead of the torque wrench" worked for me too on my old Warrior.

Calibrated feel" is my whole life now honestly. I messed up a set of landing gear bolt holes on a Skyhawk once because I trusted a torque wrench that hadn't been calibrated in like 5 years. Snapped three bolts clean off before I realized the wrench was way off. Now I just tighten by touch on anything small and have way less headaches. Broke a buddy's ancient tap trying to clean a stripped thread on a Comanche last month, we both just laughed and said "should've been calibrating by feel instead.
