Does anyone know about tightening torque for the different screws inside the iPhone ? If someone knows thread type and dimensions on the screws, it can be calculated. The length of the screws are measurable, but the type of thread in unknown for me and google ;)

I have always tightened them “finger tight”, not “He-Man” tight. I know this is not a specific lbs. of torque, but it works for me.
