22NA5-048 NUT - ANCHOR, CORNER, TWO RIVET HOLES
PART NUMBER: 22NA5-048
AIRCRAFT: Various
CONDITION: NS
DETAILS: Corner (diagonal lug) self-locking anchor nut, 1/4-28 thread, nylon locking insert, cadmium plated carbon steel
The 22NA5-048 is a corner anchor nut, sometimes called a diagonal or angle plate nut. The two rivet holes sit on a diagonal rather than in line, which lets the nut mount in a corner, along a flange radius, next to a stiffener, or anywhere an in-line two lug plate nut will not physically fit. It locks with a nylon locking insert.

Cross Reference and Interchange
Government standard reference: MS21081-4 / NAS1027 style.
ESNA builds this style with either locking insert. 22A5-048 carries the fiber insert and 22NA5-048 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.
