Product Description
The 530412 is a hex castellated nut for 0.31-24 (5/16-24 UNF) threads that secures drilled-shank bolts with a cotter pin. Steel construction aligns with AN310 castle-nut specifications for positive locking on control and structural attachments. The castellated design features slots that align with a hole in the bolt shank, allowing a cotter pin to pass through and prevent loosening under vibration.
Install on a drilled bolt or stud, torque per aircraft maintenance manual, then insert the cotter pin through aligned slots. Common in general aviation and commercial aircraft where reliable fastening of critical joints is required.
