Metallics JGSH24 Ground Screw10-32 X 3/8 Hwh Sl Green Steel Zinc (Jar 100)

Yes. The Metallics JGSH24 is a 10-32 machine screw, which is the standard tapped thread for the grounding hole in steel device and outlet boxes, so it threads straight into the box's factory ground hole. The 3/8 inch length keeps the shank from bottoming out or protruding behind the box.

100 screws per jar. Metallics packs them in a jar rather than a box, which is what most electricians want on a truck or a gang box since you can pour out a handful without spilling the lot.

3/8 inch is the usual length for bonding a pigtail or a single ground conductor to a box or a bracket. If you are stacking several conductors, a bonding jumper plus a device ground, or screwing through thicker stock, you want a longer 10-32 machine screw instead, since the 3/8 shank only has so much usable thread once a wire is wrapped under the head.

Order Metallics JGSH24. That is the manufacturer part number for the 10-32 x 3/8 inch green zinc plated steel ground screw with a slotted hex washer head, supplied 100 to a jar.

The green finish is the color convention for equipment grounding, and it is how an inspector picks out the grounding screw in a box at a glance. The JGSH24 is green over zinc plated steel, so the color is on a plated fastener rather than a bare one.

Yes. The washer head gives a wide flat bearing surface, so a wrapped bare copper ground conductor clamps directly under the head with no added washer or lug. That is the point of the washer-head profile on a grounding screw.

Anywhere there is a 10-32 tapped hole, it works, which covers metal mud rings, plaster rings, straps and mounting brackets as well as box ground holes. On unthreaded sheet metal it will not hold, since this is a machine screw and not a self-tapping one.
