NUT (P/N sl406m12a) - New Surplus

The sl406m12a is a self-locking barrel nut designed for aerospace structural joints requiring prevailing-torque retention. This cylindrical nut features an internal locking mechanism that prevents loosening from vibration and thermal cycling common in aircraft environments. Used to secure brackets, equipment mounts, and fastening points in airframe assemblies where compact nut geometry is essential.

Installation requires torquing per the applicable aircraft maintenance manual to achieve proper clamp load while engaging the self-locking feature. Verify part-number compatibility with your airframe specification before replacement to ensure correct thread size and locking characteristics.
