Metallics JFMP104SS – Frequently Asked Questions
1) Will a 1/4-20 x 2 in. flat head screw sit flush in a countersunk hole?
Yes, provided the countersink matches a standard flat head. The head on the JFMP104SS measures 0.442 to 0.477 in. across and 0.131 to 0.153 in. high, built to ASME B18.6.3-1998, so it drops into any 82 degree countersink cut for a 1/4-20 flat head machine screw and finishes level with the surface.
2) Are these screws coarse thread, and will they take a standard 1/4-20 nut?
Coarse thread, 20 threads per inch, UNC, cut to ANSI/ASME B1.1. That means they thread into any standard 1/4-20 nut, coarse-tapped hole, or 1/4-20 strut nut without an adapter. They will not fit a fine 1/4-28 tapped hole.
3) Do these Metallics machine screws meet Buy American requirements for a federal job?
No. The JFMP104SS 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, these will not satisfy it.
4) What size driver do I need for the Metallics JFMP104SS machine screws?
A #3 Phillips driver bit. The recess on these 1/4-20 flat head screws runs 0.276 in. diameter and 0.16 in. deep, so a #2 bit will cam out and chew the recess. Keep a #3 in the pouch before you start the run.
5) Can I use these stainless machine screws outdoors or in a wet area?
18-8 stainless is the right pick for general atmospheric corrosion resistance, which covers damp mechanical rooms, refrigeration equipment, and food processing machinery. It is not a marine grade, so for constant salt spray or submerged service you want 316 rather than 18-8.
6) How strong are these 18-8 stainless machine screws compared to plated steel?
Rated at 1900 lb minimum tensile with a hardness of Rockwell B85-B95. Stainless also holds its strength better than plain steel when the application sees elevated operating temperature. Note that there is no national performance standard for stainless machine screws, so those figures are published as guides.
7) How are the Metallics JFMP104SS screws packaged and what is the smallest quantity I can buy?
They ship in a jar of 100, and 100 is the order minimum. That jar quantity suits a panel build or a fixture run where you want spares on the truck rather than counting out loose pieces.
8) What trades actually use a 1/4-20 x 2 in. flat head Phillips machine screw like this?
Electrical, plumbing, and heating and air conditioning work. Typical use is bolting panels, brackets, covers, and equipment where you need a flush head and a machine thread into a tapped hole or nut. The 2 in. length gives you reach through a bracket plus a doubled plate or spacer.
