Metallics JGSH14 – Frequently Asked Questions
1) What thread size and length is the Metallics JGSH14 ground screw?
The JGSH14 is a 1/4-20 x 1/2 inch ground screw with a hex washer head and a slotted drive. The 1/4-20 thread is a coarse machine thread, so it lands in a tapped 1/4-20 hole rather than self-tapping into sheet metal.
2) Is the Metallics JGSH14 the right screw for bonding a ground wire in a device box?
Standard device boxes are tapped 10-32 for the green grounding screw, not 1/4-20. The JGSH14 is the larger 1/4-20 size, which shows up on ground bars, enclosure bonding points, strut, and equipment frames. Check the tapped hole before ordering: a 1/4-20 will not thread into a 10-32 boss.
3) Can I drive the JGSH14 ground screw with a nut driver instead of a screwdriver?
Yes. It's a hex washer head with a slot, so you can run it with a nut driver on the hex or a flat blade in the slot. In a crowded panel or box the nut driver usually gives better torque without camming out.
4) Will a 1/2 inch long ground screw be long enough for a panel ground bar or enclosure?
The 1/2 inch length under the head suits bonding to a tapped hole in a panel wall, ground bar, or enclosure where the material is thin and the screw only needs a few threads of engagement. If you're stacking a lug plus a thick bonding jumper pad, or going through a spacer, you'll want a longer 1/4-20 screw instead.
5) What is the manufacturer part number for the Metallics 1/4-20 ground screw?
Order it as Metallics JGSH14. That single model covers the 1/4-20 x 1/2 hex washer head slotted ground screw.
6) Does the hex washer head need a separate washer under it for a ground lug?
No. The washer head is integral, so it gives its own bearing surface against a lug tang or bonding jumper. Add a lock washer only if your spec or the equipment listing calls for one.
