Description
The NAS686A3K is a genuine Textron Aviation nut used to fasten, secure, or retain components during assembly of the airframe. It is fitted to the Caravan or Grand Caravan EX, King Air C90, C90A, C90GT or E90, Skyhawk, Skylane, and Stationair. It carries an export classification of ECCN EAR99.
Because the NAS686A3K 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.
Because the Cessna Caravan, Beechcraft King Air, Cessna Skyhawk, Cessna Skylane, and Cessna Stationair aircraft share extensive structure and hardware, a single part like this is often common across several variants.
Strength grade and finish define aircraft hardware, so matching the specified part keeps the joint as designed. Fitting the correct factory part the first time avoids the rework, removal, and re-inspection that an incorrect or unapproved part can trigger.
Genuine sourcing means the part matches the drawing exactly, so fit and function are known quantities rather than a gamble at installation.
These aircraft are built by Textron Aviation, which unites Cessna (founded 1927) and Beechcraft (founded 1932) under one Wichita, Kansas company since 2014. Cessna's single-engine Caravan turboprop, in production since 1984, is one of the most widely used utility aircraft in the world.
