Product Description
The AN320-6 is a castellated shear nut designed to secure drilled-shank bolts in control-system linkages and other shear-loaded joints. The hex-slotted profile accommodates a cotter pin for positive mechanical locking, preventing fastener rotation during vibration and flight operations. Manufactured to AN320 specifications, this nut is installed on drilled fasteners, torqued to specification, then safety-wired or pinned per AC 43.13-1B.
Commonly used in aircraft control systems, structural bracing, and linkage assemblies where shear loads dominate and axial clamping is minimal. The castellated design distinguishes it from standard hex nuts, enabling reliable retention without self-locking features.
