Metallics JFM110 – Frequently Asked Questions
1) How many screws come in a jar of Metallics JFM110 machine screws?
The JFM110 ships as a jar of 100 screws, and 100 count is the order minimum. So one order unit equals one 100-piece jar of 1/4-20 x 1-3/4 in. flat head slotted machine screws.
2) Does the JFM110 thread into a standard 1/4-20 tapped hole or nut?
It does. The thread is 1/4-20 UNC with 20 threads per inch, cut to ANSI/ASME B1.1, so it mates with any standard 1/4-20 UNC tapped hole, nut, or strut channel nut. Usable grip is whatever the 1-3/4 in. length leaves after your material stack.
3) Are these zinc plated screws OK for outdoor or damp locations?
These are zinc plated carbon steel, which suits dry indoor electrical work, panels, enclosures and device mounting. Zinc plating is a sacrificial coating, not stainless, so in wet, washdown or coastal exposure it will eventually corrode. For those openings go to a stainless 18-8 machine screw in the same 1/4-20 x 1-3/4 size.
4) Do these Metallics machine screws meet Buy American or ARRA requirements for a public job?
The JFM110 carries both ARRA compliant and Buy American compliant flags in the manufacturer data, with country of origin China. On federally funded work, submit those compliance designations to your spec reviewer against the specific clause in your contract, since the applicable rule varies by funding source.
5) Is the Metallics FM series a machine screw or a self tapping sheet metal screw?
FM and FMP are machine screws, fully threaded 1/4-20 UNC for a pre-tapped hole or a nut. They will not cut their own threads in sheet steel. If you are fastening into unthreaded sheet metal, use a self drilling or self tapping screw instead, or tap the hole to 1/4-20 first.
6) How much does a jar of 100 of these 1/4-20 screws weigh for shipping?
A full jar runs 1.98 lbs. Handy if you are palletizing a bulk MRO order or checking a parcel weight on a multi-jar buy.
