22NA21-62-BC NUT - ANCHOR, TWO LUG, FLOATING
PART NUMBER: 22NA21-62-BC
AIRCRAFT: Various
CONDITION: NS
DETAILS: Two lug floating self-locking anchor nut, 6-32 thread, nylon locking insert, cadmium plated carbon steel
The 22NA21-62-BC is a two lug floating anchor nut. The 6-32 nut element is retained loosely inside a staked steel bracket so it can shift laterally, which lets the screw find the hole when panel hole patterns do not line up perfectly. That float is what makes this style the standard choice for removable panels, cowlings, fillets and long access door runs where accumulated tolerance would bind a fixed nut plate. Locking is by nylon locking insert.

Cross Reference and Interchange
Government standard reference: MS21059L06K (all-metal, countersunk rivet holes).
ESNA builds this style with either locking insert. 22A21-22-62BC carries the fiber insert and 22NA21-22-62BC carries the nylon insert. The two are dimensionally the same part and are normally interchangeable, so order by whichever number your parts list calls out.
In the ESNA 22 series the 22 prefix denotes cadmium plated carbon steel, A denotes a fiber locking insert and NA denotes a nylon locking insert. The trailing dash number is the thread code, where 62 is 6-32, 82 is 8-32, 02 is 10-32, 048 is 1/4-28, 054 is 5/16-24 and 064 is 3/8-24. A BC suffix indicates 100 degree countersunk rivet holes.
