George:

This part will work for me.

From 300.10 (2011)
"....shall be mechanically secured to boxes, fittings,
cabinets, and other enclosures."

Niko:
Using your scenario above, it sounds like a heck of a lot of work to save 2 locknuts. I have to say, I have not had anyone try that kind of install.

Could you apply the same mechanical logic with EMT fittings, without locknuts inside the boxes, and the shoulder of the connectors making contact??
