Rant: The amount of guys I see using the wrong torque on LRU rack bolts is wild

Specifically on the 737 Classic forward electronics bay, those rack bolts need 35 inch-pounds, not just 'tight'. I watched a guy at my old shop in Wichita crank them down with a regular screwdriver handle, and we had a whole rack come loose in flight. How is this not basic knowledge by now? What's the most basic thing you've seen someone mess up on the line?

Ugh, I've definitely been that guy before...

Got a torque wrench just for those little guys after seeing a rack shift during a heavy check. Marked my personal 1/4-inch drive with tape at 35 inch-pounds so I never have to guess. It takes two extra seconds and saves a huge headache later. @campbell.max, I get it, we've all rushed, but that's one spot where the book is right. Seeing a rack loose in flight would ruin my whole week.
