Metallics JSPM15SS – Frequently Asked Questions
1) Will a 1 inch long 8-32 screw be too long for a flush device box?
It can be. At 1 inch of thread, mounting a receptacle or switch straight to a flush-set box leaves excess screw protruding past the yoke into the box, which eats wiring room. Use the 1 inch length where you are spanning a plaster ring, extension ring, or a recessed box, and drop to a shorter 8-32 for flush mounting.
2) How wide is the pan head, and will it cover an oversized hole in a cover plate?
Head diameter runs 0.306 to 0.322 inch with a head height of 0.085 to 0.096 inch. That is the standard ASME B18.6.3 pan head footprint for an 8-32, so it bears on a normal device or cover plate hole but will not bridge a worn or oversized opening. For that, add a flat washer or step up to a fender washer under the head.
3) Is 18-8 stainless the right choice for outdoor or damp-location electrical work?
18-8 stainless is the usual pick for wet and damp locations and coastal exteriors because it resists rust where a plated steel screw will bleed and seize. These are 18-8 stainless through the whole screw, not plated, so a scratched head does not become a corrosion point. For heavily chloride-exposed marine work, 316 stainless is the step up.
4) How many screws come in a jar, and can I buy fewer than 100?
They ship 100 to a jar, and 100 count is the order minimum. If you need a different size or a different pack quantity, Metallics offers other sizes and quantities by request.
5) Do these machine screws meet Buy American requirements for a public project?
The JSPM15SS is flagged compliant for both Buy American and ARRA, which is what a government, school or municipal procurement file typically needs on a fastener line item. Country of origin is listed as multiple, so if your contract requires a single named origin, that is the point to verify on the specific lot.
6) Are these the same as a sheet metal or self-tapping screw?
No. The JSPM15SS is a machine screw with uniform 8-32 UNC threads running the full length, so it needs a pre-threaded hole or a nut. It will not cut its own thread in sheet metal the way a self-tapping screw does. If you are fastening into bare sheet, you want a sheet metal screw or a tapped hole plus this screw.
7) What size screwdriver do I need for these slotted pan head screws?
A #2 driver. The drive is a straight slot, 0.045 to 0.054 inch wide and 0.045 to 0.058 inch deep, so a #2 flat blade seats properly without camming out. If you are running these with a power driver, a slotted bit in that width is what to load.
8) What is the tensile strength of these stainless machine screws?
80,000 psi minimum, with hardness reported as Rockwell BBS-B9S. Worth knowing before you spec it on anything structural: there is no single performance standard for stainless machine screws, so Metallics publishes tensile values as approximations. For a load-bearing connection, use a graded steel bolt rather than an 8-32 stainless machine screw.
