Metallics JSRM13 6-32 x 1-1/2 in. Round Head Slotted Machine Screws - 18-8 Stainless - Each

No. The JSRM13 is listed as not Buy American compliant and not ARRA compliant, with country of origin recorded as multiple. On a federally funded project with domestic sourcing language, these will not satisfy the requirement and you need a domestically produced fastener.

These Metallics round head slotted screws ship in a jar of 100, and 100 is the order minimum. So one buy gets you a jar, not a loose count of screws.

18-8 stainless is the austenitic 300-series alloy used where plated steel would rust, so it holds up in damp, washdown, and exterior locations better than a zinc-plated screw. Metallics lists these for the electrical, plumbing, heating and air conditioning trades. Note they are non-magnetic-grade stainless, not hardened steel, so they are a corrosion choice rather than a high-strength one.

Metallics rates these at 80,000 psi minimum tensile with a hardness of Rockwell B85 to B95. One caution straight from Metallics: tensile values for stainless screws are approximations, because there is no single performance standard for stainless machine screws. If a drawing calls out a specific grade or proof load, a graded alloy-steel screw is the safer specification.

The drive is a slot measuring 0.039 to 0.048 inch wide and 0.051 to 0.068 inch deep, so a small flat-blade cabinet-tip screwdriver is what engages it properly. The head is round, not flat or oval, 0.24 to 0.26 inch across and 0.091 to 0.103 inch high, so it sits proud on the surface rather than countersinking. If you need the head buried in the material, use a flat head screw instead.

Yes. Metallics offers other sizes and quantities in this SRM round head slotted line by request. The JSRM13 specifically is the 6-32 x 1-1/2 inch stainless version in a 100-count jar.

A jar runs 0.58 lbs, and the jar itself measures 3 x 2.15 x 3 inches. Small enough to sit in a van bin or on a service cart without eating shelf space.
