Speaking of duplex screws.. Anyone else notice if using stranded wire to the Duplex wire straight in, not to a lug, it will always loosen up after install. 100% gets looser and needs to be retightened after a month or so. Solid core not so much. Just sayin’.
Best practices for terminating stranded wire to an electrical receptacle outlet is to use a receptacle with a terminal plate to hold the stranded wire in place.
When using solid wire the wire should be curled around the terminal screw in a clockwise motion. This type of wire termination will give the best solid termination of the solid wire to the terminal screw and the receptacle.
Though the receptacle is Listed to use the wire terminal plate to terminate both stranded as well as solid wire it does not hold the solid wire tight in place. Just moving the receptacle around after terminating the solid wire so as to install and push the receptacle into the outlet box will loosen the wire connection. I would suggest if you must use the terminal plate for solid wire work the wire and receptacle into place in the wall electrical box. Then pull the receptacle out of the box just enough to expose the side terminal screws and retighten them again.
