Nut Barrel – 627773 – 0.74" DIA × 0.97" LG

Cylindrical barrel nut used in aircraft structural fastening systems where high-strength bolted joints are required through aligned structural members. The barrel design provides a deep threaded engagement area, distributing loads evenly and improving joint strength in high-stress airframe applications. It is typically installed in structural assemblies where access from one side is limited or where high clamping force and alignment stability are required.

Application:
Aircraft structural assemblies, wing and fuselage joint connections, landing gear attachments, engine mounts, and other high-load airframe fastening points requiring barrel-type nut retention

Function:
Provides a strong internal threaded anchor within a structural joint, allowing bolts to pass through mating components and engage securely while distributing load across a larger bearing surface to reduce stress concentration
