SCREW, DRIVE, ROUND HEAD

The MS21318-29 is a genuine Textron Aviation screw drive round head — a fastening or retaining hardware item used in the airframe. It is applicable to the King Air 350 Fusion, King Air 350C FM-36 & On, King Air 350C Fusion, King Air 350i, King Air 360, King Air 360C, King Air B200, B200T, B200C or B200CT, King Air B200GT, King Air B200GT Fusion or B200CGT Fusion, and Super King Air 350. It carries an export classification of ECCN EAR99. As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21318-29 is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs. Because the Beechcraft King Air aircraft share extensive structure and hardware, a single part like this is often common across several variants. Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. OEM parts arrive to the specification the type design was certified against, preserving both airworthiness and the airframe's documented configuration. Beechcraft was founded in Wichita, Kansas in 1932 by Walter and Olive Ann Beech, and has been part of Textron Aviation since 2014, uniting with Cessna and Hawker. The King Air first flew in 1964 and became the best-selling business turboprop in history — still built today as the King Air 260 and 360.
