Metallics GS20 – Frequently Asked Questions
1) Will the Metallics GS20 ground screw thread into a standard steel outlet box grounding hole?
Yes. The GS20 is a 10-32 thread, which is the standard tapped grounding hole size in steel device and outlet boxes. Length is 3/8 inch, enough to engage the tapped hole or the punched grounding boss without bottoming out in a shallow box.
2) How many Metallics GS20 ground screws come in a box?
The GS20 ships 100 screws to a box, which is how it's packed for electrical contractors and MRO stockrooms doing box-by-box grounding on a rough-in.
3) Can I use the Metallics GS20 to ground a receptacle or switch yoke instead of a metal box?
It threads into any 10-32 tapped grounding point, which covers the tapped hole in a steel box and the 10-32 hole in a device yoke or mounting strap. What it will not do is self-tap; the hole has to already be tapped 10-32 or you need a thread-cutting ground screw.
4) Is the 3/8 inch length long enough to land a ground pigtail plus a bonding jumper?
For a single conductor wrapped clockwise under the head, 3/8 inch is the usual length and gives full thread engagement in a tapped box hole. If you are stacking a pigtail and a bonding jumper, or grounding through a thicker bracket, step up to a longer 10-32 ground screw so you keep enough threads engaged.
5) What head and driver does the GS20 ground screw take?
It's a round head screw with a slotted drive, so a standard flat blade driver works. The raised round head gives the ground pigtail something to seat against when you wrap the conductor under it.
6) What is the GS20 ground screw made of, and will zinc plating hold up in a damp location?
Steel body with a zinc plated finish. Zinc plating is a general indoor corrosion coating; for wet, coastal, or corrosive environments most electricians spec stainless grounding hardware instead of plated steel.
