TDP LLDA11418-003.pdf

This is a Technical Data Package for a continuous threaded stud (NIIN: LLDA11418, Version 003) dated October 23, 2023, used in crucial shipboard systems where material failure could result in loss of life or vessel damage.

The stud specifications include Type IV, N/A style, B16 grade per ASTM-A193, hardened and tempered condition, 3/8 inch size, 5' to 8' feet length, 16 UNC thread series, Class 2A fit, and chamfered end configuration. Manufacturing and design requirements reference MIL-DTL-1222 with specific amplifications, including requirements for coating, anodizing, welding, and allied processes. Material certification is mandatory, requiring quantitative chemical and mechanical analysis per DI-MISC-81020, with traceability marking on finished items. The document requires Magnetic Particle Inspection (wet method) per T9074-AS-GIB-010/271 with acceptance per MIL-DTL-1222 and SAE J123. Government Quality Assurance at source is required with inspection procedures documented and available for review. Configuration Control and Engineering Change Proposals (ECPs) are mandatory, with all waivers and deviations requiring approval by the Contractor Officer, designated as Critical, Major, or Minor.

The quality system must comply with ISO-10012 or ANSI-Z540.3 with ISO-17025 calibration requirements, and contractors must maintain documented quality systems available for audit. All suppliers of Level I/SUBSAFE materials must submit current documented quality system procedures. Final inspection includes 100% inspection for traceability marking legibility and material verification, with zero-defect lot acceptance criteria. Certification data must be provided with signed certifications, positive and unqualified statements on material certification documents, and complete material traceability from raw material through finished component. Packaging and preservation requirements must comply with contract schedule specifications.
