Metallics JFMB83 – Frequently Asked Questions
1) Are the JFMB83 screws flat head or round head, and what driver do they take?
Flat head with a slotted drive, per the FH SL designation. Flat head means they seat flush in a countersunk hole rather than standing proud, and you drive them with a standard flat blade screwdriver, not Phillips.
2) What material and finish are the Metallics JFMB83 machine screws?
Brass machine screws, shown as MS BR in the part description. Brass is non-ferrous and non-sparking, and it's commonly specified where the fastener needs corrosion resistance or where a brass finish has to match existing plates and hardware.
3) How many screws come in the Metallics JFMB83 pack?
100 screws in a jar. The jar pack is the format electricians and maintenance crews keep on the truck or on the shelf for cover plate and device work, rather than a boxed bulk count.
4) Do I need a nut or anchor with the JFMB83 machine screws?
Machine screws thread into an existing tapped hole or a nut, they don't cut their own thread like a sheet metal or wood screw. On electrical work that tapped hole is usually already in the device strap, box, or plaster ring. If you're fastening through unthreaded material, pair them with an 8-32 nut.
5) Can I use brass 8-32 screws instead of steel ones in an electrical box?
Brass is a common substitute and is often preferred where corrosion is a concern or where a brass-colored head has to match existing trim. Brass is softer than steel, so don't overtorque with a drill. The thread is identical at 8-32, so a brass screw drops into the same tapped hole as a steel one of the same length.
6) Is the JFMB83 sold as a single screw or only by the jar?
It's a single orderable item, part number JFMB83, and that item is the jar of 100. There's no loose-piece or single-screw option under this part number.
