It’s for where bolts have to be tightened to a specific amount, and certified. Faster than writing it down. Faster to track down an error.
As others have pointed out, you’d want every single bolt on your airplane tightened to computer level precision and error control. If some stray cosmic ray strikes the wrench during the tightening process then that’s the universe telling you it’s time to go.

Most likely there would be some error detection/correction against cosmic rays
