SELF TOPPING SCREW

The MS24621-18 is a genuine Textron Aviation self topping screw used to fasten, secure, or retain components during assembly of the airframe. It is fitted to the Bonanza 36, King Air 100, King Air B200, B200T, B200C or B200CT, King Air B200GT, and King Air B200GT Fusion or B200CGT Fusion. Because the MS24621-18 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. Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. Because substitutions on type-certificated aircraft require approved data, the genuine part is the straightforward, compliant choice for this application. 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. 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. First delivered in 1947, the Bonanza earned a lasting reputation for build quality and honest handling over one of the longest production runs in aviation history.
