nutplate search

[SeanB]

I'm trying to find a single leg or corner nutplate that is countersunk for a -06screw. No luck so far. Anyone know of such an item and where to buy?

Thanks,

Yeap, B&B. Call them in the morning, their web site is inop.

GAHCO has all sorts of hardware and probably has what you want.

Thanks, guys. Checked with GAHCO earlier...no luck. Will give B&B a call tomorrow.

If you cant find what you want, put a countersunk shim in between the nutplate and the skin.

I have bought and used them.They are on page 72 of the 2011-2012 catalog. Like many things they have several names (even the old mil specs gave them different names). In this case Anchor nut, Dimpled, standard, single leg and corner.

I'm trying to visualize this, without success....... Any photos, or a longer description in 6th grade English for guys like me??

Thanks,

Sean,
Check out chapter 7 of FAA AC 43.13-1B. You can download this "must have" document from the FAA web site. It's over 400 pages, so they break it down into chapters for easier downloading. Chapter 7 details info on aircraft hardware, including nut plates [pages 7-63 through 7-68]. The info you want is on page 7-65. FYI, you will note that there are 2 part numbers shown with each photo. The numbers differ only in the last digit. Numbers ending in an odd number are passivated steel [same as what comes in your kit] Changing that last digit to the next higher "even" number, specifies the same part, but either cadmium plated or made of stainless steel [stainless nut plates are handy to use in your instrument panel, as they are non magnetic]
Single leg and corner nut plates come in flat, countersink, "normal leg" and "mini leg" sizes.

Use the link below to download chapter 7 and the other chapters of this very useful document.

I have used all of the vendors mentioned above to buy nut plates
Wicks Aircraft also carries them. An A&P friend turned me on to M&M Aerospace. They carry all the "oddball" hardware you can not find elsewhere.
They are now a division of B/E Aerospace. See

PS While Vans uses the archaic AN [army/navy] part numbers, the rest of the world has moved on to the current MS [military spec] numbering system. It's much easier to get what you want from a vendor, IF you know the proper MS part number for the nut plate in question.

Pete,
You simply fabricate a piece of aluminum [2024-T3 or 6061-T6] of a thickness which will allow you to countersink into the skin/spacer so as not to have the countersink contact the center hole of the standard nut plate. Cut the spacer slightly larger [length & width] than the nut plate. Place the spacer between the nut plate and the skin or structure. Back drill the rivet holes from the nut plate, through both the spacer and the skin. Pilot back drill the screw hole through both the spacer and the skin. You can now cleco the spacer to the skin and countersink for the needed flush screw [and rivet holes if needed]. After de-burring and any desired corrosion control steps, simply rivet the nut plate/spacer pieces to the skin or structure.
I have several photos, but they do not give enough detail to be of use. I took them with an old disposable camera.
It's a bit more work, but useful when you don't want to stop progress on your project to wait for hardware to arrive.

Just got some from B&B. Got both corner and single lug.

Call them. The web site isn't accurate.
