NUT

The AN310-4 is a genuine Textron Aviation nut used to fasten, secure, or retain components during assembly of the airframe. It fits the Baron Series B55, E55, 58 or G58, 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 Excel, XLS, XLS+, XLS Gen 2, Citation III, VI or VII, Citation M2, M2 Gen 2, M2 Gen 3, and Citation Sovereign or Sovereign+, among other compatible variants. It carries an export classification of ECCN EAR99, weighs 0.01 lbs, and measures 0.50 (L) x 0.44 (W) x 0.28 (H) in. Supplied directly by Textron Aviation as an original-equipment (OEM) part, the AN310-4 meets the manufacturer's specification and keeps the aircraft configuration-correct, with clean traceability in the maintenance records. Because the Beechcraft Baron, Cessna Caravan, Cessna Citation, Beechcraft King Air, Cessna Skyhawk, and Cessna Skylane aircraft share extensive structure and hardware, a single part like this is often common across several variants. Fastening and retaining hardware may look simple, but grade, size, and finish are specified for the joint each secures — the correct part matters. These aircraft are built by Textron Aviation, which unites Cessna (founded 1927) and Beechcraft (founded 1932) under one Wichita, Kansas company since 2014. The Baron — a twin-engine member of Beechcraft's piston line introduced in 1961 — shares much of its structure and hardware with the Bonanza.
