new to using thhn/emt

Thanks for any help. I have been reading the NEC and have passed my county's homeowner's exam to get my permit. I am going to be adding a sub and circuits to my attached garage. I need to do surface mount for the new circuits b/c of the time and trouble to redo the drywall already up. I therefore will be using EMT and THHN for my job. I understand that the conduit is attached to a set screw connector and the fitting goes into the junction box/panel and is locknutted to secure the conduit/connector into place. I will be running a separate grounding conductor. Is there some sort of bushing/clamp that has to be used inside the set screw connector for protection of the wires as it comes out of the connector? Also does the THHN have to be clamped in any way like Romex has to be clamped as it comes into a box?

No one seems to say anything about a bushing, so I think it's not needed, but I don't want to miss something so obvious that no one talks about it either.

Thank you very much,

Scott
