Metallics JFM103 – Frequently Asked Questions
1) Will the Metallics JFM103 machine screw thread into a standard 1/4-20 tapped hole or nut?
Yes. The JFM103 is a 1/4-20 UNC screw at 20 threads per inch, cut to ANSI/ASME B1.1, so it mates with any standard 1/4-20 coarse tapped hole, nut, or strut channel nut. Overall length is 1-1/2 inches.
2) Is a zinc plated steel machine screw okay for outdoor or wet locations?
The JFM103 is zinc plated steel made from AISI 1006 to 1022 low carbon steel. Zinc plating is a mild corrosion barrier meant for dry indoor service, panel work, and enclosure interiors. For exterior, damp, or washdown locations, move to a stainless machine screw of the same 1/4-20 x 1-1/2 size.
3) Are these Metallics screws Buy American or ARRA compliant for a government job?
No. The JFM103 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your contract carries a domestic sourcing clause, this screw will not satisfy it.
4) How many 1/4-20 x 1-1/2 flat head slotted screws come in a pack?
These Metallics flat head machine screws ship in a jar of 100, which is also the order minimum. Plan the count against your job rather than buying singles.
5) Do I need a nut with these flat head machine screws, or do they tap their own thread?
Machine screws do not form their own thread. The JFM103 needs a mating 1/4-20 nut or a hole already tapped 1/4-20 coarse. Nuts and washers are not included in the jar of 100, so order them separately.
6) What trades use the Metallics FM and FMP series machine screws?
The FM and FMP flat head series is stocked for electrical, plumbing, heating and air conditioning work: device and enclosure mounting, strap and bracket fastening, and panel hardware where a flush head is wanted.
7) How much does a jar of 100 of these 1/4-20 x 1-1/2 screws weigh?
The jar comes in at 1.83 lbs. Useful if you are totaling out a van load or a shipment of multiple jars.
