Metallics JGSH25 – Frequently Asked Questions
1) Is the Metallics JGSH25 ground screw the right thread for a standard metal outlet box ground hole?
Yes. The JGSH25 is an 8-32 thread, which is the thread tapped into the grounding hole of standard steel device boxes and mud rings. Length is 1/4 inch, so it seats in the tapped hole without bottoming out or projecting into the wiring space.
2) Will a 1/4 inch long ground screw be long enough to catch the threads in a box?
For a tapped grounding hole in a steel box or bracket, 1/4 inch of 8-32 thread is enough engagement, since the box wall is thin and the hole is threaded through. If you are running the screw through a thicker bracket, a stacked pigtail, or a plaster ring plus box wall, step up to a longer 8-32 ground screw instead.
3) What driver do I need for the Metallics JGSH25 ground screw?
It is a hex washer head, so a 1/4 inch nut driver or hex socket drives it. The washer face under the head spreads clamping load on the bonding conductor and keeps it from slipping out of the hole as you tighten.
4) Is the JGSH25 a green ground screw or plain steel?
CD in the Metallics JGSH25 designation is the cadmium-style plated finish, not a green-colored head. If your inspector or job spec calls for a green-headed screw to identify the equipment grounding point, order a green ground screw rather than this one.
5) What is the part number to reorder the Metallics 8-32 x 1/4 hex washer head ground screw?
The manufacturer part number is JGSH25 from Metallics. That single number covers the 8-32 x 1/4 hex washer head CD ground screw.
6) Can I use the JGSH25 as a general purpose machine screw for mounting devices?
Mechanically it is an 8-32 machine screw and will thread anywhere 8-32 is tapped, but the head style is hex washer rather than the slotted or combo head used on device mounting screws. For bonding jumpers and grounding pigtails at the box, this is the intended use.
