Metallics JFM33SS – Frequently Asked Questions

1) Will a 10-32 flat head machine screw sit flush in a countersunk device box or plate?
Yes, that is what the flat head is for. The Metallics JFM33SS has a flat head measuring 0.333 to 0.362 in. across with a head height of 0.098 to 0.116 in., so in an 82 degree countersunk hole of matching size it seats flush with the surface. If the hole in your plate or box is not countersunk, the head will stand proud by roughly a tenth of an inch and you want a round or pan head instead.
2) Is 10-32 the right thread for electrical box and device screws?
10-32 is the standard thread for outlet box, device, and cover plate screws in US electrical work, and that is what the JFM33SS cuts: 32 threads per inch in the UNF series, made to ANSI/ASME B1.1. It threads into the tapped 10-32 holes in steel boxes, mud rings, and fixture straps. Note the 1/2 in. length, which is short, so it suits thin plates and brackets rather than deep stack-ups.
3) Do these Metallics machine screws meet Buy American or ARRA requirements for a government job?
No. The JFM33SS is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries domestic sourcing language, these will not satisfy it.
4) Are these stainless screws OK for outdoor, damp, or food plant use?
18-8 stainless is specified for general atmospheric corrosion resistance, which covers damp locations, refrigeration equipment, and food processing machinery where plated steel would rust. It also holds strength better than steel as operating temperatures rise. For heavy chloride exposure such as coastal salt spray or pool chemical rooms, 18-8 is not the top tier; 316 stainless is the usual step up there.
5) How many Metallics JFM33SS screws come in a jar?
They ship 100 to a jar, and the jar is the order minimum, so one unit gets you 100 pieces of the 10-32 x 1/2 in. flat head slotted screw rather than a single screw. Jar weight is 0.49 lbs.
6) What dimensional standard do these flat head screws conform to, for submittal purposes?
Head and body dimensions follow ASME B18.6.3-1998, threads follow ANSI/ASME B1.1, and the material is called out to SAE. That combination is what a submittal reviewer looks for on an inch-series slotted flat head machine screw.
7) Can I get this 10-32 flat head stainless screw in a longer length or a bigger box?
The JFM33SS itself is fixed at 10-32 x 1/2 in. in a 100-piece jar, but other sizes and quantities in the Metallics FM and FMP machine screw series are available by request. Tell us the diameter, length, and count you need and we will match it from the series.
8) Are these screws only for electrical work, or can I use them in HVAC and plumbing too?
Metallics lists the field application as the electrical, plumbing, heating and air conditioning industries. In practice it is a general purpose stainless fastener for panel, bracket, and equipment assembly across all three trades, which is why a lot of MRO crews stock a jar on the truck.
