SCREW, TAPPING, 100 DEGREE CSK

The MS21207-6-10 is a genuine Textron Aviation screw tapping 100 degree csk — a fastening or retaining hardware item used in the airframe. It is fitted to the Baron Series B55, E55, 58 or G58, Bonanza 36, Bonanza F33, G33, F33A or F33C, King Air 350 Fusion, King Air 350C FM-36 & On, King Air 350C Fusion, King Air 350i, King Air 360, King Air 360C, and King Air B200, B200T, B200C or B200CT, among other compatible variants. It carries an export classification of ECCN EAR99. Because the MS21207-6-10 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. Across the Beechcraft Baron, Bonanza, and King Air fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. Built by Beechcraft — the Wichita, Kansas manufacturer founded in 1932 and part of Textron Aviation since 2014 — this part carries a name long associated with rugged, capable aircraft. The Beechcraft Baron, introduced in 1961 as a twin-engine development of the Bonanza, carried Beechcraft's reputation for solid handling into a capable light twin.
