This is a Material Ordering Data sheet for fasteners under MIL-DTL-1222, a federal specification for studs, bolts, screws, and nuts for applications requiring high reliability.

The specification applies to fasteners intended for general, high-temperature, high-strength, and corrosive environment applications, including elevated temperatures, immersion in seawater, salt/marine environments, high preloads, and high shock loadings. The ordering data specifies Level I alloy steel socket head capscrews with the part number M1222N1N14C20SDNN, configured as hexagonal, CRES 316 material, cold worked nuts. The fasteners must be 0.875 inches in size with 9UNC-2B thread series and class of fit. Additional requirements include chemical analysis and mechanical property testing with reported results. Containers must be marked per MIL-STD-129 with reference to DLA Procurement Note C20. The specification mandates that all referenced documents cited in the solicitation must be to the latest revision at time of award. The Material Ordering Data was prepared by Susan Trezise (Code C/244.4) and references IDN 4523A 5345-0214 and ICN 38LNG12308.
