Part #??? I’m replacing camloc mounting.

[xcrmckenna]

I just replaced all my cowl camlocs with the Skybolt kit today. It turned out great.

 

One of the four camlocs around the prop and engine has previously been replaced with a screw. I would like to replace the other three camlocs with the same screw type hardware circled in red, but I have no idea what this part is called or where to look on Aircraft Spruce. Thanks for any help.

That is an anchor nut.

I’m guessing it would be the two lug floating anchor but?

You need MS21059L3 plate nut.  L3 being 10-32 NF screw size.

The original hardware seems flush mounted...

The replacement anchor nut seems to have used a different type of rivet to hold it in place...

See if you can use a flush mount / rivet this time as well...

PP thoughts only...

The nut plate appears to be held on with Pop rivets.  You’ll want to use MS 20426AD3- 3 or 4 length.

Do you have a good guess on the size of drill bit to drill out the old camloc nut plate?

#40 or 3/32”

You might consider replacing the 2 aluminum plates as well.  You’ll need to measure the thickness in an unworn section.  Likely 0.050 or 0.063” 2024T3 aluminum and Ms20426AD4- 3 or-4 length and some epoxy for additional strength.

Can I use a brake rivet tool to press the rivet or do I need one of those forcept rivet compressor. Can’t think of the name right now.

Either a rivet squeezer with flat sets or a pneumatic rivet gun, a flat set and a bucking bar.

Where can you get replacement cowl camlock's at?

Not sure about a D model, but on my Ovation, its this series, I think the length is a 5.  There is a little number on the face of the camloc.  That's the length.

Hey Charles, if you're around my neighborhood on a weekend, drop by, I've got plenty of rivets and squeezers, we can knock that out in a few minutes

I have a Bravo, so should be the same as the Ovation.

The Skybolt hardware @xcrmckenna mentioned are superior, and you don't have to order the whole replacement kit if you're just looking for a few

How so?  Skybolt and Milspec both manufacture stainless steel camloc compatible fasteners.  Milspec sells single parts too.

[jaylw314]

The skybolt fasteners have larger flanges than the small camlocs (Dzus) which helps keep it from pulling through fiberglass over time, although it means you might need a longer fastener than the old ones.  The big camlocs from Skybolt seem pretty much equivalent.

Mooney used Camloc 2700 (smaller diameter) and 4000 (larger diameter) fasteners on many models.  Earlier ones used screws.  Earlier battery doors used Southco (Lion) fasteners before switching to 2700 Camloc fasteners.

Dzus were more common on WW2 airplanes.

I have no idea what I'm talking about, I just know them as big and little thing-a-ma-jiggies

I believe the fasteners that hold the left side, square, fuselage panel on many of the short and medium bodied birds is a Dzus product. The are the only flat headed fasteners on the whole airframe IIRC.

Dzus fastener has a spring receptacle like this.

I’m not sure what the backside looks like but I’m pretty sure they say Dzus on the head!

For some reason on my J, some of the #5s on the lower cowl are too tight, I had replaced with #6s. May have something to do with the anti chafe tape used.
