Common Parts Questions — Cessna 210 Centurion
The Centurion's complex retractable gear uses NAS6204 through NAS6210 close-tolerance bolts at pivot points, AN4 through AN6 bolts on actuator attach brackets, and MS21042 series all-metal locknuts. Hydraulic line B-nut fittings are MS fittings, not AN.
Cowl attach uses AN3-series Dzus-equivalent fasteners on later models, plus AN525 washer-head screws. Earlier models use older AN507 round-head screws. Check your IPC for the transition serial number for your airplane.
