Metallics JSRM141 6-32 x 1-3/4 in. Round Head Slotted Machine Screws - 18-8 Stainless - Each

No. The JSRM141 is marked not Buy American compliant and not ARRA compliant, with country of origin listed as multiple. For a project with domestic-sourcing requirements you will need a fastener specifically certified as domestic.

The material is 18-8 stainless steel, the common austenitic grade used where plated-steel screws would rust. That makes it a reasonable choice for exterior boxes, wet-location covers, marine and coastal jobs, and food-service or washdown areas. Note the drive is slotted, not Phillips or combo, so plan on a flat-blade driver.

Head width runs 0.24 to 0.26 inch and head height 0.091 to 0.103 inch, so the dome sits roughly a tenth of an inch above the surface on a quarter-inch-wide bearing face. A round head is a raised head, not countersunk, so it will not sit flush in a countersunk hole. If you need the head buried, specify a flat head instead.

They ship in a jar, with an order minimum of 100 count. So the buying unit is the 100-piece jar rather than loose pieces, which is the format most electricians and MRO stockrooms want on the truck or the shelf.

It is a machine screw, meaning a uniform 6-32 straight thread that needs a mating tapped hole or a nut. It will not form its own thread in sheet metal. If you are fastening into unthreaded metal, use a self-tapping or sheet metal screw instead, or tap the hole 6-32 first.

Tensile strength is listed at 80,000 psi minimum with hardness of Rockwell B85-B95. Metallics notes that tensile values for stainless screws are approximations only, since there is no single performance standard for stainless machine screws. For a graded, certified strength value you need a carbon steel screw to an SAE grade rather than 18-8 stainless.

The SRM series covers other sizes and quantities by request, so if 1-3/4 inch is longer or shorter than you need in 6-32 round head slotted stainless, the family has additional lengths available.
