EXHIBIT C 60589403 DATA__.pdf

This is a Material Ordering Data (MOD) sheet for MIL-DTL-1222, specifying requirements for studs, bolts, screws, and nuts for high-reliability applications dated 08 December 2020. The document establishes the baseline specification and ordering parameters for fasteners intended for general, high-temperature, high-strength, and corrosive environment applications requiring elevated reliability. These fasteners are designed for diverse applications including elevated temperatures, immersion in seawater, salt/marine environments, high preloads, and high shock loadings.

The ordering data specifies a Double End Stud, TY-III, Style B, Class A fastener in Alloy 400, As Formed or Stress Relieved condition with a socket head cap screw style configuration. The fastener dimensions are 1/2" diameter by 4-3/4" long with Stud End 15/16" long and Nut End 2-1/4" long, using 13UNC-5 thread series and 13UNC-2A Nut End. Chemical analysis and mechanical property test results are required, with certification and marking in accordance with MIL-STD-129 per DLA Procurement Note C20. All unit, intermediate, and shipping containers must be marked according to MIL-STD-129. The document identifies the part number as M122SST3N8CB76NANN and requires compliance with the latest revision of referenced specifications at time of award.
