NUT

The MS21044N6 is a genuine Textron Aviation nut — a fastening or retaining hardware item used in the airframe. It fits the Baron Series B55, E55, 58 or G58, Bonanza 36, Caravan or Grand Caravan EX, Citation CJ1 or CJ1+, Citation CJ2 or CJ2+, Citation CJ3, CJ3+, CJ3+ Gen 2, CJ3 Gen 3, Citation CJ4, CJ4 Gen 2, CJ4 Gen 3, Citation III, VI or VII, Citation V, Ultra, Encore or Encore+, and King Air C90, C90A, C90GT or E90, among other compatible variants. It carries an export classification of ECCN EAR99, weighs 0.02 lbs, and measures 0.64 (L) x 0.57 (W) x 0.46 (H) in. Because the MS21044N6 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 Baron, Beechcraft Bonanza, Cessna Caravan, Cessna Citation, Beechcraft King Air, Cessna Skyhawk, and Cessna Skylane fleet, correctly identified factory parts like this keep every airframe consistent and configuration-correct. Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. Both the Cessna and Beechcraft lines are supported today by Textron Aviation, formed in 2014 to unite the two historic Wichita manufacturers with Hawker. The Beechcraft Baron, introduced in 1961 as a twin-engine development of the Bonanza, carried Beechcraft's reputation for solid handling into a capable light twin.
