I was reading an old maintenance manual and the torque spec for a Cessna 172's nose gear bolt shocked me

It was only 35 inch-pounds, which felt crazy low for something that holds the front wheel on. Found it in a PDF from the 1970s I downloaded last week. Anyone else ever get surprised by how light the torque is on a critical component?

Makes you wonder about all the things we over-tighten just because it feels right. Phone chargers get yanked out, jar lids get cranked down until the plastic strips. We assume tighter is always safer, but that manual proves sometimes the engineers want it just tight enough, and not a bit more.

Feels like that time I tried to tighten a water bottle cap to "German spec" and almost couldn't get it off again.

That 35 inch-pounds is wild... I torqued a lawnmower blade bolt to more than that once. Makes you think about how they figure that stuff out.
