Metallics JFM129 – Frequently Asked Questions

1) Will these screws meet a Buy American or ARRA requirement on a federal job?
No. The JFM129 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded project with domestic sourcing language, these will not clear the submittal.
2) How thick a material can I fasten with a 3 inch machine screw?
The 3 inch figure is the usable length measured from the top of the flat head down, because flat head screws are measured overall. Stack your material thicknesses plus enough thread for the nut and you can work up to just under 3 inches of grip. For thinner assemblies you want a shorter screw so you are not left with excess thread past the nut.
3) What does a jar of 100 of these 5/16-18 x 3 inch screws weigh for shipping or shelf planning?
The packed jar runs 5.7 lbs, at 7.25 inches high and 4.5 by 4.5 inches. That fits a standard van bin or shop shelf without repacking.
4) Do you carry other lengths and diameters in the Metallics flat head slotted machine screw line?
Yes. JFM129 is one size in the Metallics FM and FMP machine screw series, and other diameters, lengths and pack quantities are available on request. If you are standardizing a building or a truck stock, pick the sizes off the same series so the drive and head style stay consistent.
