SCREW, TAPPING, 100 DEGREE CSK

The MS21207-4-8 is a genuine Textron Aviation screw tapping 100 degree csk — a fastening or retaining hardware item used in the airframe. It is applicable to the King Air B200, B200T, B200C or B200CT, King Air C90, C90A, C90GT or E90, King Air C90GTi, and King Air C90GTx. Because the MS21207-4-8 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. Across the Beechcraft King Air fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. Strength grade and finish define aircraft hardware, so matching the specified part keeps the joint as designed. Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation. On a certificated airframe, part provenance matters as much as the part itself; genuine factory sourcing settles that question up front. 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 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.
