Happy Breffast!
1.2Nm is barely finger tight (11 in-lb). What are you using to measure torque?
Can you tap and install a threaded insert?
EDIT: or a larger self-tapping screw

My first guess is that middle screw isn't the same thread/size as what you are attaching it to. It doesn't look stripped to me. If you did manage to strip the threads my first course of action would be to clean up the threads and if needed chase both the bolt and nut with the correct size tap and die.

layertone, did you ever receive a suggestion to correct this or receive help from the vendor? I just attempted to finish the install on my LVX6048 and I think I also have a defective screw block for my L2 and N connection. I am not able to get it screwed to any reasonable tightness at all, and I am just using a hand screwdriver.

All these style inverters have those same cheap plastic style connections. Barely screw them in and soon as it barely feels like your grasping anything quit. Your on the verge of stripping it out

Those terminal blocks are awful. On my brand new LV6548, I snapped off the metal moving piece that clamps down on the wire as you tighten the screw. I hardly tightened it and somehow it's supposed to sustain 55A. I learned the hard way that it's best not to use solid-core wire and if using THHN (stranded, but thick strands) make sure the wire is flattened out a bit going in and not round so the clamping force is evenly distributed. Annoying...

Thread chaser, not a tap and die. A thread chaser will not remove material, a tap or die will.

Buy a good set of thread chasers, like a Snap On set and you will use those and not the tap and die for chasing threads.I have a tap and die set and I'm not afraid to use it.
Seriously, I have a tap and die set that I've used more often to chase threads than to actually create threads. I a tool whore, but there's only so much room in my tool chest.
Leave the tap and die for what they are designed for.
