Joe so you would fail this based on 110.3(B)?
So using a nut and bolt or a ground clip to terminate the grounding conductor would also be a violation?

This is the type of enforcement that makes people avoid inspections.

The clamp machine screw can (minus the clamp) can safely perform the function of grounding the box.

Being forced to change this by an inspector would only be for the inspectors amusement as it certainly is not a NEC violation.

We are discussing the hole for the clamp screw! The use of a bolt and nut or a "LISTED" clip is acceptable.

When you install cables, such as MC or AC under a clamp and terminate the EBJ (the pigtail) where do you terminate it?

If the box has the threaded hole, that's where it should be.

If there was an accident, you would not be able to satisfy the judge and jury that it was OK because you said so.

Any inspector who allows this is not doing their job.

Again, put the inspector's hat on for a while!
