While it is true, that they do sell pre-assembled ground screws + pigtail wires, that is only a matter of convenience for people with more money than time. Normal people make their own pigtails out of common wire. The ground screw in the back of the metal box is tapped #10-32 and any short 10-32 machine screw will suffice.

The code requires that all ground conductors be connected so that the continuity of the ground is not interrupted if the device is removed. This requires a pigtail, but making a pigtail for ground conductors requires a specific approach: First, twist the bare ground conductors together for several turns, and then cut off all but one for each device in the electrical box. The way I see it, I would think that using MC cable and metal junctions, the rest of the circuit's boxes would already be grounded due to the metal MC cable conduit being clamped to each of the metal boxes (connected to the already installed/grounded box). Do I need to create a pigtail for the ground in each of the remaining boxes and connect . Bare Buchannan splice caps were the device used to splice the pigtails. The boxes has no tapped hole for a ground screw, so the clamp screws were used to connect a pigtail to. There were no devices that required a GEC connection, so the the GEC pigtail only entered the the box, to ground the box and make it accessible.

I'm trying to ground an outlet in my home to the metal of the junction box. I'm using a grounding pigtail of 14AWG wire with a 10/32 terminal attached to one end.

Is your EMT acting as your ground or are you also running a dedicated equipment grounding conductor? My take: 250.118 "The equipment grounding conductor run with or enclosing the circuit conductors shall be one or more or a combination of the following.". I suppose if everything is properly bonded back to the panel then it would work and not technically violate . If there truly is no 10-32 tapped hole in the box, then I'd remove the grounding wires from the box mounting screws, nut them to a pair of 12AWG bare pigtails, and land one pigtail on the GFCI's grounding screw and the other on . I just had an inspector call me on "not using crimp connectors to pigtail ground wires in plastic boxes."

250.118 accepts EMT as a EGC, grounding type receptacles need no bonding jumper with a properly bonded metal box A ground pigtail is a short length of wire that connects the ground wire from an electrical system to multiple devices or components, effectively “piggybacking” off the main ground. Ground pigtails are commonly used in electrical panels, junction boxes, and various electrical installations to create a reliable grounding path.

It used to be required to "maintain continuity" with the available equipment grounds at each junction box. So conduit ground and wire ground went together at each box. About ten years ago they changed the wording so you only need to ground the box with the wire ground (maintain continuity) when a splice is made in the box.

Section 250.110 outlines the grounding requirements for electrical equipment, including junction boxes. Junction boxes must be grounded to provide a path for fault current to return to the source and to prevent electrical shock. Using an approved grounding method, you must connect the grounding conductor to the junction box.

A metal electrical box must have a separate grounding pigtail connected to it, then connected to all the ground wires in that box. Looping the feed wire ground around the grounding screw and using the end for a pigtail connection has been disallowed, beginning with the 2020 National Electrical Code (NFPA 70) article 250.148(C).
