Metallics JFMB79 – Frequently Asked Questions
1) What size and type of screw is the Metallics JFMB79?
It's a 12-24 x 3/4 inch flat head slotted machine screw in brass. Machine thread, so it threads into a tapped hole or a nut rather than cutting its own threads in wood or sheet metal.
2) What thread does the Metallics JFMB79 mate with?
12-24 UNC. It will only start in a hole tapped 12-24 or a 12-24 nut. It will not thread into a 10-32 hole, which is the thread most device boxes and cover screws use, so confirm the tapped size in your box, strut or enclosure before ordering.
3) How many Metallics JFMB79 screws come in a jar?
The JFMB79 is packed 100 screws to a jar, which is how it ships for bench or truck stock rather than loose count.
4) Will a flat head screw sit flush in my cover plate or channel?
Flat head means a countersunk 82 degree head that seats flush when the hole is countersunk or dimpled for it. On a plain drilled hole with no countersink, the head will stand proud. If you need a flush look without countersinking, a different head style is the better pick.
5) Why choose a brass screw over steel for electrical work?
Brass is non-magnetic, corrosion resistant, and conductive, which is why it shows up on grounding and bonding connections and in damp or exterior locations where a plated steel screw would rust. If you want a plated steel fastener for strength instead, that's a different part number.
6) Do I need a Phillips driver for the Metallics JFMB79?
No. The JFMB79 is slotted, so it takes a flat blade screwdriver. A 12-24 head takes a reasonably wide blade, so match the tip to the slot to avoid chewing the brass.
7) What is the Metallics part number for the 12-24 x 3/4 brass flat head slotted screw?
Order it as Metallics JFMB79. That's the manufacturer part number for the 12-24 x 3/4 inch flat head slotted brass machine screw in the 100 count jar.
