Metallics JSRM27 10-32 x 1 in. Round Head Slotted Machine Screws - 18-8 Stainless - Each

18-8 stainless is the austenitic grade used where plated steel would rust, so it holds up in wet, humid, and exterior locations, wash-down areas, and near coastal air. Tensile strength is listed at 80,000 psi minimum with a hardness of Rockwell B85-B95. Note that tensile figures for stainless machine screws are approximations; there is no single performance standard for them. If you need a defined strength class for a structural connection, use a graded steel fastener instead.

No. The JSRM27 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded job with domestic sourcing requirements these will not pass, and you need a domestically produced fastener instead.

Slotted drive only. The slot measures 0.05 to 0.06 in. wide and 0.065 to 0.087 in. deep, so a flat blade tip in that thickness range seats properly. A Phillips bit will not engage and will cam out and chew the head. If your crew is running Phillips or square-drive bits exclusively, specify a different drive type.

They ship in a jar, 100 screws, and 100 is the order minimum. The packed jar weighs 0.87 lbs. For an MRO cart or a van stock bin this is a single countable unit rather than a loose bulk count, which makes it straightforward to standardize across a facility.

It is a machine screw, meaning a uniform 10-32 machine thread with a blunt end. It needs a pre-threaded hole or a nut; it will not cut its own threads in sheet metal or form a thread in a drilled pilot hole. For fastening into unthreaded sheet steel you want a self-tapping or sheet metal screw, not this.
