Re: Gounding Screw
.
, that is what I would be SAYING! if it was my crew .
There is nothing confusing about this it is about making a simple thing into a world event
.That's my point, why go thru all the waste of time and hassle, NEXT TIME JUST USE A GREEN GROUND SCREW AND IF YOU DON'T HAVE ONE STOP BY THE SUPPLY HOUSE AND BUY A BOX OF THE DARN THINGS FOR CRYING OUT LOUD

As for my self I will use what is free and code compliant, we never run out of spare clamp screws as the guys pull the extra clamps out of the boxes.

I will now jump back into my time machine and head back to finish my tea with King Nebuchadnezar, and the rest of my Babylonian amigos, GOOD BYE !
Yea you are, but to each his own, if you want to use clamp screws more power to you
!Isn't that what this thread is all about, A GROUNDING SCREW, and no it does not have to be green, use what ever the flavor of the month is.
I will do just that Sir, thank you very much, unless there happens to be a hot pink with green poka dots screw in my pouch then and only then will I JHR consider using IT instead of the green screw.

!Re: Gounding Screw
Provided that the clamp is removed the 10/32 screw Is allowed to be used as the bonding means. The fact that it is a bonding termination it is identified by the conductor.
I like to see a flat head screw rather than an oval head to provide a better connection.
A grounding screw provides the best grounding means. Why not use it? NEC is a MIN. requirement romeo

Re: Gounding Screw
It seems to me that the point is to prove a inspector wrong not to provide the best bonding means. If a contractor does not have grounding screws in his truck it is time to take inventory. I wonder what other items he will substitute to finish the job. I as an inspector am not always correct but I am right more than I am wrong,I do my best to be sure of that.
A grounding screw having a flat head with a hex head will provide a much better connection than a round head screw designed to hold a clamp, and anyone that disagrees to that is not trying to do the best work. Just my opinion

romeo,
You want a pan head screw. A flat head screw is one like supplied to connect the device to the box and is not suitable for use with bonding conductors.

Re: Gounding Screw
Do you have any reason to believe that one 10/32 screw holds a solid conductor in place better than another?
I doubt its that with me as I have never had inspector ask me about the screws I use.

romeo,
What makes you think that one is better than the other? Have you ever checked different types with a micro ohm meter? I'd be willing to bet that if the screws are tightened to the same torque value there would be no difference in the meter reading.

Re: Gounding Screw
What is the significance of the following?
250.126 Identification of Wiring Device Termination
The terminal for the connection of the equipment grounding conductor shall be identified by one of the following :
(1) A green, not readily removable terminal screw with a hexagonal head.
(2) A green hexagonal, not readily removable terminal nut.
(3) A green pressure wire connector.......etc.

Re: Gounding Screw
For the factory installed screw on devices.
It has nothing to do with the screw used to bond a box.
It is significant as it is a code requirement.

Re: Gounding Screw
Don, if he is indeed talking about a flat head screw, which I don't think he is; I'd be willing to bet you will find a difference in resistance, because surface making contact with a flat head is only along inside diameter of terminal as opposed to flat surface of pan head.

Larry,
I agree, but he is really talking about a pan head versus a round head.
