MS21069L4 ANCHOR NUT
Great material. Unbeatable price.
NUT,TWO LUG ANCHOR MS21069L06
Everything arrived on time as ordered
Great for where you need a smaller nut plate.
Available in a minature and full size rivet spacing. Both are equally tough.
Excellent nut plate for limited space applications and maximum structural strength is not required.
High quality item, but it is very fragile looking. Definitely, not for heavy duty use. For my purposes, I ended up ordering Part #AN366F-1032A MS21078-3, which served my purposes much better.
This anchor nut was WAY smaller than I thought it would have been. The 10/32 thread needed to be re-tapped before it was usable.
