Overview

All metal floating anchor nuts. MS21059 ( F5000 ) and MS21061 ( F2000 ).

Anchor nuts are designed for blind mounted applications where it is impractical to use hex nuts or where it is desirable to have an attached nut for ease of maintenance.

Need for lower cowling. I had to give it a good cleaning which I used StrutWipe, also sold by AS.

I ordered these with two other parts which were out of stock. I was OK with that but needed the anchor nuts sooner. They came the next day! And of course they are very good quality. Thank you ACS!

Perfect for providing an attached nut that moves just enough to insure alignment.

These were for the rear seat rear legs in a cessna 172L. The originals had gotten stripped out over time, and werent the floating type. These floating anchors allowed more wiggle room in getting everything to go together. I was a little disappointed with the shipping time. Ordered them around 430 pm est on a monday with priority mail shipping, and they arrived Thursday afternoon about 3 PM. I thought they would arrive a day sooner.

A little confusing to find the standard two lug floating nut plate as they are listed in the right hand column and the picture is the second picture which must be selected. But these are the nut plates which are the same size as the standard non-floating and work well.

The picture shows a single lug and is a little confusing regarding the number for a two lug floating nut plate

The F5000 anchor nuts we offer require 3/32" diameter rivets for installation.
