NAS1423

NAS1423 is a National Aerospace Standard (NAS) that specifies plain hexagon nuts which are drilled, typically jam nuts with a thin profile. These nuts are commonly used in aerospace and other high-precision applications due to their safety wire locking capabilities and compact design.

 

Product Description:

Nut Type: Plain Hexagon, Drilled, Jam, Thin
Standard: NAS1423 (National Aerospace Standard)
Locking Mechanism: Drilled holes enable the use of safety wire for positive locking, ensuring vibration resistance in dynamic environments.

Materials:

  • AISI 4140 / 4340 / 8740: High-strength alloy steels offering excellent fatigue resistance.

  • A286 (Alloy 660): Austenitic iron-nickel-chromium alloy with superior oxidation resistance and high strength at elevated temperatures.

Key Features:

  • Precision Machining: Manufactured to tight tolerances for high-performance assemblies.

  • Thin Profile: Space-saving design ideal for limited-clearance applications.

  • Drilled for Locking: Cross-drilled design allows for safety wiring, enhancing reliability.

  • Corrosion & Heat Resistance: Especially suitable for demanding aerospace and defense environments.

Applications:

NAS1423 nuts are widely used in:

  • Aircraft engines and structural assemblies

  • Avionics mounts and vibration-prone areas

  • Defense-grade equipment and missile systems

  • Satellite hardware and space-bound components
