Metallics JSRM22 10-24 x 3/4 in. Round Head Slotted Machine Screws - 18-8 Stainless - Each

No. The JSRM22 machine screws are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. If your contract carries a domestic sourcing clause, these will not satisfy it.

The JSRM22 has a slotted drive, which is what most electrical device and box hardware has historically used, so it matches existing screws in a panel or box you are adding to. The slot measures 0.050 to 0.060 inch wide and 0.065 to 0.087 inch deep, so a standard cabinet-tip flat blade seats properly. If your crew runs Phillips bits exclusively on a driver, a Phillips-drive 10-24 is the easier choice for speed; the slot is better where you want feel and control to avoid overtightening on a thin box ear.

18-8 stainless is the material, which is the common austenitic grade used for general corrosion resistance, so these hold up in damp and outdoor-exposed locations far better than plated carbon steel screws. For direct salt spray or coastal exposure, 316 stainless is the step up.

Tensile strength is 80,000 psi minimum with a hardness of Rockwell B85 to B95. Worth knowing: there is no single performance standard for stainless machine screws, so stainless tensile figures are approximations. If you need a certified strength value for a structural or engineered connection, a graded carbon steel fastener is the right call instead.

They ship in a jar of 100 pieces, which is the order minimum. The jar weighs 0.7 lbs. That quantity suits an MRO crib or a service van restock rather than a single repair.

Metallics lists the field application as the electrical, plumbing, heating and air conditioning industries. In practice that means device and box mounting, strap and bracket attachment, panel covers, and general equipment fastening into tapped holes or with a matching 10-24 nut. They thread into a tapped hole or nut, not into wood or drywall.
