Metallics JSRM147 10-32 x 1-3/4 in. Round Head Slotted Machine Screws - 18-8 Stainless - Each

No. The JSRM147 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded project with domestic sourcing requirements you will need a domestically produced fastener instead.

The material is 18-8 stainless, so it holds up in damp, outdoor and washdown locations far better than a zinc plated steel screw, and it will not bleed rust onto a cover plate or enclosure. 18-8 is the common 300 series austenitic stainless used for general corrosion resistance, not a marine 316 grade, so for direct salt spray exposure specify 316 instead.

The JSRM147 is listed at 80,000 psi minimum tensile with a hardness of Rockwell B85-B95. That puts it below a hardened grade 5 or grade 8 steel fastener, so it is a general mounting and device screw, not a structural one. Note too that tensile figures for stainless machine screws are approximations, since there is no single performance standard for them.

Head width runs 0.334 to 0.359 inch with a head height of 0.123 to 0.137 inch. The round profile sits proud of the surface rather than flush, so it covers a slightly oversized or worn mounting hole, but it is not a countersunk substitute. If you need the head buried flat in the material, use a flat head screw instead.

They come in a jar, 100 count, and 100 is the order minimum. That is a shop-stock quantity rather than a loose handful, which suits a service van or an MRO bin where 10-32 device screws get consumed steadily. Other sizes and quantities can be requested.

No. A machine screw like the JSRM147 has a straight, uniform 32 TPI machine thread with no point, so it only works in a pre-tapped hole or with a nut. For wood framing use a wood screw, and for hollow drywall use a toggle or self-drilling anchor.
