Fred: You get a green tag from this inspector.

Yes, I will be there in SLC, haven't missed one since 1981!

I am an AHJ and I would not fail someone for using the remaining screw for the grounding conductor. I would however fail you if you wrapped it around the screw the wrong way! ( It has happened more times than I can recall.) The wire has to wrap around the screw clockwise so that the wire tightens up. (Righty tighty, lefty loosey) I think that is how it is spelled!?

After reading this topic and another like it it seems that the local inspector could like using the 10-32 clamp screw or he may not. No one posted and code saying you can't so it will be up to the town your working in I guess.
I also would like to point out not one old work box in my truck has any indication of which hole the ground wire should be installed under.
My opinion is I use the extra 10-32 they give you with the box and toss the extra clamp. I like it and it works.

While we are talking about this extra 10-32, why in the heck is the screw on deep old works a hardened screw? It's not on the reg depth ones and is very tough on my cutters

Joey D,- I have no idea why the box screws are hardened, they are a pain.
Try using a 32 tooth blade in your hacksaw, works for me!

Joe, with all due respect you are taking this one way out there. Sunday I am taking a grounding and bonding course. I will bring this up as the first question. I wonder how long it will be batted around!

Why do you routinely remove unused clamps?

It gives me extra space to tuck the wires and I guess that is how I was taught.

I would like to ask a question on this, what type of lock nut is holding the clamp. If I had jurisdition and the contractor continued the practice, [and I see no problem in the code with this] couldn't you request a bonding bushing on the clamp? It's the only way to know you have a true bond.
