NSN Format:
Each item within NSG 53 is assigned a unique National Stock Number (NSN) for identification and tracking purposes. The NSN format for this group typically follows this pattern:
13-character NSN:
- First two digits: Federal Supply Group (FSG) code - 53 for Hardware and Abrasives
- First four digits: Federal Supply Class (FSC) code - specific to the type of hardware or abrasive
- Next nine characters: National Item Identification Number (NIIN) - unique identifier for the specific item
Examples:
- NSN 5305-00-123-4567: Screw, flat head, Phillips drive, stainless steel
- NSN 5350-00-987-6543: Abrasive disk, silicon carbide, 120 grit
Benefits of NSG 53:
- Standardization: Provides a common language for describing and identifying hardware and abrasive items across NATO member countries.
- Interoperability: Enables the use of standardized components in NATO equipment and facilities, regardless of the country of origin.
- Procurement: Simplifies the procurement process for NATO member countries by providing a common reference system for item specifications.
- Logistics: Streamlines the logistics of supply and maintenance for NATO forces.
Additional Notes:
- NSG 53 is aligned with the US Federal Supply Classification (FSC) system, allowing for easy identification of compatible items.
- The specific items covered by NSG 53 may be subject to change due to updates and revisions to the NATO Standardization Agreements.
Conclusion:
NATO Supply Group 53 plays a vital role in ensuring the operational effectiveness of NATO forces by providing a standardized system for identifying and procuring hardware and abrasive items. This system promotes interoperability, simplifies logistics, and ultimately contributes to the success of NATO missions.
