MS21046C4E - Nut

Part number MS21046C4E is a military-standard all-metal self-locking hex nut designed for high-strength fastening applications in aerospace and vibration-prone environments. This compact prevailing-torque nut features a deformed top locking section that maintains clamp load and resists loosening without requiring a separate lock washer or insert.

Manufactured from corrosion-resistant metal alloy material, the nut is commonly used in aircraft structures, engine compartments, avionics assemblies, and other critical mechanical fastening systems where reliability and vibration resistance are essential.
