SCREW, TAPPING, 100 DEGREE CSK

The MS21207-8-8 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 Bonanza 36, King Air 100, 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, and King Air B200GT, among other compatible variants. It carries an export classification of ECCN EAR99. Because the MS21207-8-8 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 Beechcraft Bonanza and King Air 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. 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 Bonanza is widely regarded as holding the longest production run of any aircraft — from its 1947 debut until Textron announced in November 2025 that it would wind down Bonanza and Baron production as the order backlog clears.
