Metallics JFM9 – Frequently Asked Questions
1) Will these Metallics screws meet a Buy American or ARRA requirement on a federal job?
No. The JFM9 machine screws are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. If the contract carries a domestic sourcing clause, these will not satisfy it.
2) Does the flat head on the Metallics JFM9 sit flush, and what countersink does it need?
Flat head, so it seats flush in a countersunk hole. The head measures 0.38 to 0.412 in. across and 0.112 to 0.132 in. high, so the countersink has to be at least that wide to bury the head. On unprepped sheet metal with only a drilled through-hole the head will stand proud by roughly the head height.
3) How many screws come in a JFM9 order, and how are they packed?
They ship in a jar, with a 100 piece minimum order. Total packed weight is 1.039 lbs. Plan the count against your job, since it is a bulk jar rather than a small card of a few pieces.
4) Is the zinc finish on these screws OK outdoors or in a damp location?
The JFM9 is carbon steel with a zinc plating, which is a mild indoor corrosion coating. It holds up in dry interior electrical, plumbing and HVAC work. For wet locations, exterior runs or corrosive environments, move to a stainless machine screw of the same 12-24 x 1 in. size.
5) How much material can a 1 inch 12-24 screw grip?
Fastener length is 1 in. On a flat head screw that length is measured from the top of the head, since the head sinks into the countersink, so the full inch is your grip plus thread engagement. Subtract your material thickness to see how much thread is left in the tapped hole or for a nut.
6) What dimensional standard do these flat head machine screws conform to?
Head geometry follows ASME B18.6.3-1998 and the threads follow ANSI/ASME B1.1. That matters if your submittal calls out a standard screw dimension, because the head width and countersink angle will match any other B18.6.3 flat head of the same size from another maker.
