Metallics GSH21 – Frequently Asked Questions
1) Will the Metallics GSH21 ground screw thread into a standard steel outlet box ground hole?
Yes. The GSH21 is a 10-32 x 3/8 inch machine screw, which is the thread size tapped into the grounding hole of standard steel device and outlet boxes. The 3/8 inch length keeps the screw inside the box rather than bottoming out behind it.
2) Is the GSH21 a self-tapping screw, or does the box need to be pre-tapped?
It is a machine screw with a 10-32 thread and a dog point, not a self-drilling or self-tapping screw. The box or enclosure needs an existing tapped 10-32 grounding hole. If you are grounding into untapped sheet metal, you need a self-tapping ground screw instead.
3) What does the dog point on this ground screw actually do for an electrician?
The dog point is an unthreaded pilot tip on the end of the screw. It lines the screw up with the tapped hole in the box before the threads engage, so you can start it one-handed in a crowded box without cross-threading. Handy work when you are grounding boxes overhead on a trim-out.
4) Why is this grounding screw green, and does the color matter for inspection?
Green is the identifying color for equipment grounding in the trade, and a green-headed screw tells an inspector or the next electrician at a glance that the terminal is the ground. The GSH21 is green over zinc-plated steel.
5) Will a 3/8 inch long ground screw hold enough wire for a 12 AWG pigtail?
Yes for normal use. A 3/8 inch 10-32 ground screw gives enough thread engagement in a tapped box hole to clamp a looped bare copper pigtail of the sizes used on branch circuits. If you are stacking a bonding jumper plus a larger conductor under the head, step up to a longer 10-32 ground screw so you keep full thread engagement.
6) How many ground screws come in a box of Metallics GSH21?
They ship 100 screws to a box, which is the practical buy for anyone grounding boxes by the floor or by the building rather than one device at a time.
7) What is the Metallics part number to reorder these ground screws by?
Order by GSH21. That is the Metallics manufacturer part number for the green 10-32 x 3/8 dog point ground screw in the 100-piece box.
