The MS21043-5 is a self-locking hex nut with an extended washer and all-metal prevailing-torque design. This corrosion and heat-resistant steel fastener features a 5/16-24 UNJF-3B internal thread conforming to Military Standard MS21043. The extended washer base distributes load across a wider surface area, reducing bearing stress on composite or thin-gauge materials.
The integral locking mechanism resists vibration loosening without thread-locking compounds. Used in airframe and nacelle applications where reliable fastening under flight loads is critical. Install on clean, dry threads and torque per MS/NAS specifications or aircraft maintenance manual requirements.
