Common Parts Questions — Cessna 172 Skyhawk
The Cessna 172 primarily uses AN3 through AN6 series bolts throughout the airframe. AN3-4A through AN3-20A are standard for control surface hinges and fairings, while AN4 and AN5 bolts are common in engine mount and firewall applications. Always verify grip length against AC 43.13-1B and the 172 Maintenance Manual.
AN365 all-metal self-locking nuts dominate high-vibration zones (engine baffles, exhaust heat shields). AN310 castle nuts with MS24665 cotter pins are standard on control linkages per FAA AC 43.13-1B. AN960 and AN970 washers accompany most structural bolt installations.
Yes. All our AN/MS-rated fasteners are traceable to FAA Form 8130-3 Airworthiness Approval Tags from FAA-approved DER sources. Certificates are included with every shipment and available as PDF download from your order page.
AN/MS/NAS hardware manufactured to spec and accompanied by a valid 8130-3 is FAA-acceptable for certified aircraft under Part 91. Your A&P or IA is responsible for final installation sign-off. EAB and experimental 172-based builds have no restriction.
