| 1 | Material Traceability | 15% | Heat number, chemical composition, raw-material origin, and a batch-linked material certificate. | Every production batch is traceable from finished bolt to the original titanium material certificate. | Full batch traceability: 5; partial records: 3; no traceability: 0. |
| 2 | Grade and Specification Control | 13% | Declared titanium grade, drawing revision, dimensional standard, and applicable fastener specification such as ASTM F467 or ASTM F468 where relevant. | The supplier confirms the exact grade, thread form, dimensions, tolerance class, and governing standard before production. | Complete specification match: 5; minor clarification needed: 3; unclear specification: 0. |
| 3 | Mechanical Testing Capability | 12% | Tensile, yield, elongation, hardness, and proof-load test records for the specified grade and size. | Tests are performed per the purchase specification, with sample identification and recorded results. | In-house or accredited testing with reports: 5; outsourced testing: 3; no records: 0. |
| 4 | Dimensional and Thread Inspection | 12% | Inspection records for length, head dimensions, pitch, major diameter, thread gauge results, and visual defects. | Calibrated gauges and a documented sampling plan are used for every production lot. | 100% critical-feature control: 5; sampling only: 3; undocumented inspection: 0. |
| 5 | Quality Management System | 10% | Current quality-management certificate, internal audit records, corrective-action procedure, and complaint-handling process. | A valid ISO 9001 certificate is available and its scope covers fastener manufacturing or processing. | Valid certificate with matching scope: 5; system evidence without certification: 3; no system evidence: 0. |
| 6 | Surface Finish and Galling Control | 10% | Surface-roughness data, cleaning process, coating or lubrication details, and installation torque test results where required. | The supplier demonstrates controlled surface treatment and verifies that threads do not seize during specified installation testing. | Validated process and test data: 5; process description only: 3; no control plan: 0. |
| 7 | Production Capacity and Lead-Time Reliability | 9% | Declared monthly capacity, standard production lead time, sample lead time, and delivery-performance records. | Capacity is supported by equipment information and recent delivery records rather than an unsupported claim. | Documented on-time performance: 5; capacity declaration only: 3; no evidence: 0. |
| 8 | Inspection and Laboratory Independence | 7% | Calibration certificates, laboratory capability, inspector qualifications, and third-party inspection arrangements. | Critical tests use calibrated equipment; external laboratories should preferably be accredited to ISO/IEC 17025. | Independent accredited testing: 5; internal calibrated testing: 3; unverifiable testing: 0. |
| 9 | Packaging, Marking, and Export Documentation | 6% | Lot marking, corrosion-protective packaging, quantity verification, commercial invoice, packing list, and certificate of conformity. | Packaging prevents contamination and mechanical damage, and every carton is linked to the production lot. | Complete export and lot documentation: 5; basic documents: 3; missing lot identification: 0. |
| 10 | Sample Approval and Technical Support | 6% | Pre-production sample, inspection report, drawing review, engineering response time, and corrective-action records. | The supplier provides samples for approval and closes documented technical issues before mass production. | Structured approval process: 5; informal sample process: 3; no sample control: 0. |
