Metallics JFM63SS – Frequently Asked Questions
1) Will a 6-32 x 1 in. machine screw thread into a standard device box or switch plate tapped hole?
Yes. The Metallics JFM63SS is a 6-32 UNC screw cut to the ANSI/ASME B1.1 thread standard with 32 threads per inch, which is the thread used on outlet box, switch and receptacle mounting holes. At 1 inch long it gives extra reach for deep-set boxes or when you are stacking plaster rings and spacers behind the device.
2) Will the flat head on these 6-32 stainless screws sit flush in a countersunk hole?
It will, provided the hole is countersunk at the standard 82 degree angle for an ASME B18.6.3 flat head. The head measures 0.238 to 0.262 in. across and 0.069 to 0.083 in. high, so it seats below the surface in a properly chamfered hole. Dropped into a plain drilled hole with no countersink, the head stands proud.
3) Do these Metallics stainless screws meet Buy American or ARRA requirements on a federal job?
No. The JFM63SS 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, this screw will not satisfy it.
4) Are these stainless machine screws OK for damp, washdown or refrigeration work?
That is what the 18-8 stainless is for. Metallics specs this screw for general atmospheric corrosion resistance and calls out food processing machinery and refrigeration equipment as typical uses. Stainless also holds its strength better than plain steel when the application runs warm.
5) How much load will a 6-32 18-8 stainless machine screw take?
Rated at 550 lb minimum tensile, with a hardness of Rockwell B85-B95. Worth knowing that there is no national performance standard for stainless machine screws, so Metallics publishes those figures as a guide rather than a certified grade. For structural or high-torque fastening, use a graded steel bolt instead.
6) How are these 6-32 screws packaged, and what is the minimum I can buy?
They ship in a jar of 100, which is also the order minimum. The packed jar weighs 0.392 lbs and measures 3 x 3 x 2.15 in., so it drops into a van bin or service cart without repacking.
7) Is a 1 inch 6-32 screw too long for mounting a device to a standard box?
Often, yes. The 1 inch length is meant for deeper stack-ups, plaster rings, spacers, or thick cover assemblies. Mounting a receptacle flat to a flush box usually wants a shorter 6-32, and the extra thread here will bottom out or sit back inside the box. Measure your stack-up before committing to the 1 inch.
8) What driver fits the slot on the Metallics JFM63SS screw?
A flat blade. The drive is slotted, with the slot running 0.039 to 0.048 in. wide and 0.024 to 0.038 in. deep, so a #1 or small #2 cabinet-tip screwdriver seats properly. A wide carpenter's blade will ride up out of the slot and cam out on stainless, which galls easily.
