A National Stock Number (NSN) part type represents a standardized 13-digit material classification used by NATO militaries, the U.S. Department of Defense (DoD), and government procurement agencies to index, track, and manage logistical inventory.
At Just NSN Parts, owned and operated by ASAP Semiconductor, we maintain an extensive, searchable directory of aviation, defense, and industrial NSN part types spanning everything from precision structural airframe components to specialized electromechanical assemblies.

Our alphanumeric catalog organizes millions of active, hard-to-find, and obsolete NSN components into primary operational classifications for streamlined identification:
-
Airframe & Structural Components: High-tensile structural brackets, fairings, panel assemblies, skin doublers, and hinge mechanisms engineered for commercial and defense aircraft maintenance.
-
Fluid Systems & Hydraulic Hardware: Precision valves, actuation manifolds, hose assemblies, high-pressure seals, and fluid regulation fittings built for extreme operational pressures.
-
Avionics & Electromechanical Parts: Aircraft sensors, circuit breakers, wiring harnesses, relays, switches, and guidance system modules complying with strict military specifications.
-
Propulsion & Engine System Spares: Turbine blades, fuel nozzles, gaskets, shroud assemblies, and engine mounting hardware designed for harsh thermal environments.
-
Standardized Fasteners & Hardware: Military-standard (MS, NAS, BAC, AS) bolts, nuts, rivets, pins, and quick-release fasteners supporting MRO overhauls and tactical readiness.
Understanding National Stock Numbers (NSN) & Defense Logistics
Federal Supply Classification (FSC): The first 4 digits of an NSN identify the broad commodity group and class of the part, such as screws or airframe components.
National Item Identification Number (NIIN): The final 9 digits provide the unique identification of the item and include the 2-digit National Codification Bureau (NCB) code.
CAGE Code: A 5-character code that identifies the manufacturer or government supplier associated with the NSN-indexed part.
