SCREW

The CM3558-10-8G1 is a genuine Textron Aviation screw — a fastening or retaining hardware item used in the airframe. It is fitted to the Skyhawk and Skylane. It carries an export classification of ECCN EAR99. Because the CM3558-10-8G1 is an original-equipment (OEM) part sourced directly from Textron Aviation, it matches the exact specification and placement called out in the aircraft's type design and maintenance data — assurance a generic substitute cannot offer. Parts like this are shared across the Cessna Skyhawk and Skylane aircraft, reflecting how much structure and hardware these models have in common. Strength grade and finish define aircraft hardware, so matching the specified part keeps the joint as designed. The value of an OEM part is as much in its paperwork and pedigree as its metal — both of which an aircraft's records require. Genuine factory parts carry the documentation and traceability that maintenance and airworthiness records depend on — assurance a look-alike substitute cannot provide. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation. Cessna traces to the company Clyde Cessna founded in Wichita, Kansas in 1927; Textron Inc. acquired it in 1992, and since 2014 it has anchored Textron Aviation alongside Beechcraft and Hawker. The Cessna 172 Skyhawk is the most-produced aircraft in history, with more than 44,000 built since 1956, and remains in production under Textron Aviation.
