NUT,SLFLKG,EXTENDED WASHER,HEXAGON (P/N ms21043-6) - New Surplus

The MS21043-6 is an all-metal self-locking hex nut with an extended washer base designed for aerospace fastening applications. Manufactured from corrosion and heat-resistant steel, this prevailing-torque nut prevents fastener loosening under vibration and thermal cycling in aircraft structures. The extended washer ring distributes clamping load across a larger surface area, reducing stress concentration on airframe materials.

Commonly used to secure brackets, equipment mounts, and structural attachments to fuselage and wing components. Installation requires torque application per aircraft maintenance manual specifications and MS21043 standards to achieve proper prevailing torque.
