MS21049-L3K two lug countersunk nutplate with all-metal locking element, NS condition.
Part Number: MS21049-L3K
Part Type: Two Lug Countersunk Nutplate
Condition: NS
Thread: 10-32 (.1900-32 UNJF-3B per NASM25027)
The MS21049-L3K is a two lug all-metal self-locking plate nut with a 100 degree countersunk nut body, so a flush screw head sits level with the outer skin. All-metal locking means it locks by deformed thread rather than by a fiber or nylon insert, which is why it carries a 450 F rating.
