NUT

The MS21245-7 is a genuine Textron Aviation nut used to fasten, secure, or retain components during assembly of the airframe. It is fitted to the Citation X, Citation X+, King Air C90, C90A, C90GT or E90, King Air C90GTi, and King Air C90GTx. It carries an export classification of ECCN 9A991. As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21245-7 is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs. Parts like this are shared across the Cessna Citation and Beechcraft 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. Traceable OEM hardware keeps an aircraft's maintenance records defensible at annual, pre-purchase, and pre-buy inspections. 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. These aircraft are built by Textron Aviation, which unites Cessna (founded 1927) and Beechcraft (founded 1932) under one Wichita, Kansas company since 2014. The Citation family is the best-selling line of business jets ever built, and more than 7,500 have been delivered worldwide.
