Metallics JFMB76 – Frequently Asked Questions
1) Are these Metallics 12-24 screws brass or plated steel?
Brass. The JFMB76 is a solid brass machine screw, which is what gets specified where a non-magnetic or corrosion-resistant fastener is wanted, and where the brass finish is meant to be seen on a cover plate. If you need the strength of steel for a structural or load-bearing connection, a brass screw is the wrong choice.
2) Will the JFMB76 work for mounting devices and cover plates in a steel electrical box?
Yes, provided the tapped hole is 12-24. That is the thread on this screw, and it is the common tapped size in steel outlet and switch boxes, mounting brackets, and plaster rings. Watch the length: at 1/2 inch it gives you enough engagement for a device ear or plate, but if you are stacking spacers or a thick mud ring you will need a longer screw. The countersunk flat head needs a chamfered or countersunk hole to pull flush.
3) Is the JFMB76 screw a flat head or a round head, and what driver does it take?
Flat head, slotted drive. The flat head seats flush in a countersunk hole, so it sits level with a cover plate or bracket face rather than standing proud. You drive it with a standard flat blade screwdriver, not a Phillips or square bit.
4) How many screws come in a jar of Metallics JFMB76?
100 screws per jar. Metallics packages these in a jar rather than a bag or box, which is what electricians and MRO stockrooms keep on the truck or bin shelf for repeat device and cover plate work. Ordering is by the jar, so one unit gets you the full 100 count.
5) What is the Metallics part number to order for a 12-24 x 1/2 brass flat head slotted screw?
JFMB76 is the Metallics catalog number for the 12-24 x 1/2 inch brass flat head slotted machine screw, supplied 100 to a jar. Order by that number to get the brass version rather than a plated steel equivalent.
