SCREW

The MS21262-43 is a genuine Textron Aviation screw used to fasten, secure, or retain components during assembly of the airframe. It is fitted to the Citation CJ4, CJ4 Gen 2, CJ4 Gen 3, Citation Excel, XLS, XLS+, XLS Gen 2, and Citation Sovereign or Sovereign+. It carries an export classification of ECCN EAR99, weighs 0.01 lbs, and measures 0.93 (L) x 0.31 (W) x 0.31 (H) in. Supplied directly by Textron Aviation as an original-equipment (OEM) part, the MS21262-43 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records. Parts like this are shared across the Cessna Citation 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 aircraft parts are governed by strict airworthiness and traceability rules, fitting the OEM part rather than an unapproved equivalent keeps the installation eligible and the aircraft's records clean. Because this is a component for a type-certificated aircraft, using the manufacturer's part keeps the installation within approved configuration and simplifies compliance. The Cessna name is among the most recognized in aviation — founded in Wichita, Kansas in 1927 and part of Textron since 1992, today a cornerstone of Textron Aviation. The Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
