Metallics JFMP85SS – Frequently Asked Questions
1) Will 8-32 flat head screws work for mounting device plates and switch covers in standard electrical boxes?
8-32 is the standard thread for device and cover plate mounting in outlet and switch boxes, and the Metallics JFMP85SS is an 8-32 x 3/4 in. flat head Phillips machine screw in 18-8 stainless. The 3/4 inch length gives you more reach than the short screws that ship with most devices, useful when a plate sits proud of a mud ring or over added spacers. Head width runs 0.285 to 0.312 in. and head height 0.084 to 0.1 in., so it sits flush in a countersunk plate hole.
2) Is this screw coarse or fine thread, and will it match an existing 8-32 tapped hole?
The JFMP85SS is 32 threads per inch, UNC, made to ANSI/ASME B1.1. Any standard 8-32 tapped hole or 8-32 nut will take it, which covers nearly all electrical device yokes, cover plates, and enclosure mounting ears. Head and body dimensions follow ASME B18.6.3-1998.
3) Can I use these stainless machine screws outdoors or in a washdown area?
18-8 stainless is specified for general atmospheric corrosion resistance, and these are used in food processing machinery and refrigeration equipment, so exterior boxes, damp locations, and washdown environments are within what the material is intended for. Stainless also holds its strength better than plain steel as application temperatures rise.
4) How do these Metallics 8-32 screws come packaged, and what is the minimum I can buy?
They ship in a jar of 100 count, and 100 is the order minimum. Jar packaging suits a van stock or a shop bench bin rather than a single-fixture repair. Other sizes and quantities are available by request.
5) Do these Metallics machine screws meet Buy American or ARRA requirements on a public job?
The JFMP85SS is flagged compliant for both Buy American and ARRA. Country of origin is China. On a federally funded project, confirm which standard your contract actually invokes, since the two are applied differently.
6) Why choose a flat head instead of a round or pan head machine screw for plate work?
A flat head is made to pull down into a countersunk or chamfered hole and finish flush, which is what cover plates, escutcheons, and faceplates are drilled for. With a head height of 0.084 to 0.1 in. the JFMP85SS disappears into that countersink. If the hole you are working with is a straight drilled hole with no chamfer, a pan or round head is the better pick, since a flat head will only sit on top and rock.
7) What driver bit do I need for the Metallics JFMP85SS machine screw?
A #2 Phillips bit. The recess is 0.182 in. in diameter and 0.11 in. deep, so a #1 will cam out and a #3 won't seat. If you're running these with a driver, back the clutch off, stainless galls easily in a tapped hole.
