Metallics JSRM74 10-24 x 1-3/4 in. Round Head Slotted Machine Screws - 18-8 Stainless - Each

It will not sit flush. The JSRM74 has a round head measuring 0.334 to 0.359 inch across and 0.123 to 0.137 inch high, so it stands proud of the surface. For a flush finish in a countersunk hole, such as a device cover plate, you want a flat head screw instead. Round head is the right choice when the screw bears on an untapered hole or a slotted bracket.

No. The JSRM74 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. If your contract carries a domestic sourcing requirement, these will not satisfy it.

Yes. These are 18-8 stainless, the austenitic grade used where plated steel screws would rust out, so they hold up in wet locations, exterior boxes, and washdown areas. Metallics lists the application as electrical, plumbing, heating and air conditioning work.

Tensile strength is 80,000 psi minimum with a hardness of Rockwell B85-B95. Metallics notes that tensile values for stainless screws are approximations, since there is no single performance standard for stainless machine screws, so for structural or high-torque fastening a graded steel fastener is the better call.

They ship in a jar of 100, which is the order minimum for the JSRM74. There is no single-piece option, so plan on 100 per jar and order multiples for larger jobs.

No, the jar contains machine screws only. Machine screws thread into a tapped hole or take a separate nut, so if you are through-bolting a bracket you will need to order 10-24 hex or machine screw nuts and any flat washers separately.

A jar runs 1.27 lbs. Dimensions on the jar are 3 x 2.7 x 3 inches, which matters if you are consolidating small parts into a van stock bin or a job box.
