I didn't remember the exact torque number but it was very low so I decided to put some blue loctite on the screws just in case.

I still don't quite understand why you used loctite blue (sorry I am not familiar with it) for torquing purpose. If I am not wrong, loctite blue is a kind of sealant applied on screw threads to prevent it from possible leaking. So loctite blue doesn't really help you torque the screws to 7 ft-lbs. Is this correct?

No, locttite blue is not a sealant. Loctite Blue is a "threadlock" to prevent nuts and bolts from loosening.
