Product Description
The AN310-4 is a steel castellated hex nut with 1/4-28 UNF threads designed for aircraft control linkages and structural assemblies. The castellated design features radial slots that align with a drilled bolt shank, allowing a cotter pin to pass through for positive locking under vibration. Installation requires torquing the bolt to specification, rotating the nut until a slot aligns with the hole, then inserting and bending the cotter pin.
This dual-retention method prevents loosening during flight operations. Follow AC 43.13-1B safety wire practices and verify applicability in your aircraft's maintenance documentation.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
