Test specimen fasteners must be the same type, style, and diameter as the production lot and must be manufactured from the same starting material, using the same manufacturing techniques as the production lot, and must be heat treated (if required) along with the production lot. 3.13 Thread Forming - The following provides the official interpretation of paragraph 4.5.2.7 of MIL-DTL-1222. 3.13.1 In order to qualify for "Alternate Mechanical Testing" found in MIL-DTL-1222J paragraph 4.5.2.7 and utilize the mechanical properties for the starting bar stock in lieu of performing yield strength or proof stress testing on finished fasteners, all of the subsequent provisions found in MIL-DTL-1222J paragraphs 4.5.2.7 a through e must be met. If any single provision is not met, all required mechanical testing must be performed on the finished full sized fasteners. These provisions are explained as follows: a. Proper product lot control and traceability must be in place. b. No heat treatment (including hot heading and hot forming), cold forming, drawing, rolling and thread rolling may be performed on the starting bar, fastener blanks or finished fasteners after the completion of the mechanical testing on the starting bar. c. and d. The proper size starting bar must be selected to ensure mechanical properties of finished fasteners are represented by the mechanical properties of the starting bar. e. The mandatory testing, axial tensile (studs) and wedge tensile (screws and bolts) must be performed on full sized fasteners. Note that there is a typographical error in paragraph 4.5.2.7 and that the axial load test is a mandatory test that must be performed on studs as required in paragraph 4.5.2.7.e. 3.13.2 Thread rolling is a cold working process and is not considered to be a machining or grinding operation. Therefore, fasteners which have rolled threads do not satisfy the provisions of MIL-DTL-1222J paragraph 4.5.2.7.b and are not eligible for the "Alternate Mechanical Testing" provision. 3.13.3 Thread rolling alone is not a sufficient cold working process to qualify a fastener to be in the cold worked (CW) condition. This condition is only applicable to some 300 series stainless steel studs, screws and nuts. These CW condition fasteners must be manufactured from cold worked bar stock or be cold headed in order to qualify. The threads may subsequently be rolled, machined or ground. Testing of the finished fasteners and/or reporting of the starting bar stock material properties is subject to the same provisions found in MIL-DTL-1222J paragraph 4.5.2.7 and discussed above. 3.14 Specification Change - For QQ-N-281, Class B material: 1 - Footnote 9 to Table II of QQ-N-281 does not apply. 2 - When starting material is Round Bar greater than 3" dia, the mechanical properties of Hex Bar apply. 3.15 Internal Threads - All internal threads must be formed by cutting. Cold forming of internal threads is not acceptable. 3.16 Thread Inspection Requirements - All threads on threaded parts must be inspected using appropriate inspection methods, inspection systems, and inspection gages/instruments in accordance with FED-STD-H28 series. Substitution of thecommercial equivalent inspection in accordance with ASME B1 series is acceptable. 3.16.1 System 21 of FED-STD-H28/20 must be used as a minimum inspection requirement for threads when the design drawing or design specification does not specify an inspection requirement. 3.16.2 For Navy and Shipyard drawings, system 21 of FED-STD-H28/20 may be substituted for System 22 without further Navy approval when the design drawing invokes System 22 and does not cite governing specifications that specifically require system 22. System 22 of FED-STD-H28/20 must be used when the drawing references other governing specifications that specifically require System 22, such as certain thread types of MIL-DTL-1222. 3.16.3 A written request for concurrence must be submitted when utilizing alternative measuring equipment or measuring systems not applicable to the specified inspection system. 3.17 Welding or Brazing - When welding, brazing, and allied processes are required, as invoked by Section C paragraph 3 requirements, they must be in accordance with S9074-AR-GIB-010A/278, 0900-LP-001-7000 for brazing of piping and pressure vessel applications, or S9074-AQ-GIB-010/248 for brazing of other applications. For all production and repair welding and brazing personnel and procedures must be qualified under S9074-AQ-GIB-010/248 or 0900-LP-001-7000, as applicable. Procedures and Qualification Data must be submitted for review and approval prior to performing any welding or brazing. 3.18 Component Identification Description (CID) - When applicable drawing(s) and/or specification(s) specify that a nameplate or identification plate is required, the CID number ( ;CID 884305950; ) must be added. When no plate is specified, an identification plate in accordance with MIL-DTL-15024, Type "C" on brass or Type "H" on aluminum must be securely attached to each assembly showing the above CID number. No assembly must be shipped without the CID number attached. 3.19 Certificate of Compliance - (SPECIAL EMPHASIS MATERIAL) The Contractor must prepare and submit a certificate of compliance certifying that the items/components furnished under this contract comply with the requirements of the procurement document, including any/all invoked specifications and drawings. 3.20 Configuration Control - The Contractor must maintain the total equipment baseline configuration. For items of proprietary design, Contractor drawings showing the latest assembly configuration must be provided to the Government in electronic (C4) format. Definitions are provided elsewhere in the Contract/Purchase Order. 3.20.1 Waivers/Deviations - All waivers and deviations, regardless of significance or classification require review and approval by the Contracting Officer. Waivers and Deviations must be designated as Critical, Major, or Minor. The Contractor must provide a copy of this request to the QAR. Re...
