Rivnuts

Jeffrey Steenson · Post by **Jeffrey Steenson** » Fri Feb 17, 2012 9:22 pm

I've been trying to find some information about when to use rivnuts and when
nutplates are preferred, but the information is pretty sketchy. Rivnuts
seem very convenient - but should they always be keyed so they won't spin
around. I was thinking of them for wing tips and inspection plates. If any
experienced builders can advise .... Many thanks!

I've never tried rivnuts and I've heard they can come loose and it can make
it difficult to remove a screw. I have tried a product called 'nutserts'
from Wicks that seem really great. They have teeth and when swedged into a
piece of sheet they really grip. You can install them with the same tool
you would use for a rivnut.

I've used lots of rivnuts and they are OK not great. The trick is to use
just enough pull to pull tight but not strip the threads. If the metal is
always the same thickness no problem but I seem to strip one on each
different thickness.
My rule of thumb is to use rivnuts on non-structural applications, and
nutplates for structural parts and panels.

I've used a mix of nutplates, rivnuts, and a few nutserts.. I usually mix up a
tiny bit of proseal and coat the outside of the rivnut in the proseal before I
install it in the hole.. I've used 8-32 nutserts on all the inspection panels,
and I've had screws in and out of them a few times so far, and no problems with
them coming loose..

I suppose if you used keyed rivnuts you could do without the proseal.. I got a
great deal on a few hundred non-keyed and went for it..

Hi Jeffrey !

Never had much luck with rivnuts - they do tend to loosen &
spin, although maybe putting them in with epoxy or ProSeal might help !

Wayne had a good stock of clipnuts - these are ideal for
wing & tail tips. You might check out his web site at:

www.irishfield.on.ca

If you need a fair number of them, I'm sure he'd mail them.

Hi all,
One other comment on rivnut use. Put a dab of locktite under the head before pulling, and be sure that it is clean before running the screw in. I do have a few in 97MR with no regrets yet. Curt

Of course a keyed rivnut is a great place to initiate a crack. I stuck
with nutplates (about $0.30 ea at Oshkosh or Sun'n Fun) and the clipnuts
from Wayne. Love the clipnuts - Quick, easy, no risk of not being able
to remove the screw. Also Locktite doesn't work near as well unless
there is iron present in the joint or you use the activator.

Dear Jeff;

G'day from OZ !

I used a number of rivnuts in our Rebel and have been fairly happy with the
results (though I have had a few "spin" (and yes, they were keyed in), and a
couple of others strip themselves of thread if you do them up too tightly).

I wouldn't use them in areas of high load unless there are LOTS of them
spread out
evenly to share the load .

Thanks to one and all for the helpful reponses to my question about rivnuts.
I'll be sure to follow up on the clipnut suggestion.

Why have i not heard of anyone using FLUSH rivnuts. Seems logical to use for access inspection covers, wing tips, etc anywhere you want to use a screw but need a flush application. No more install work than a rivit. Nut plates would be far more work except where structural strength is required. Comments ???

Rivnuts--- Nutserts basically the same thing. I used a whole bunch of them on just such locations.

On thin sheet they have a BAD habit of spinning free with any slight seizing of the screw. Then your are "screwed" as well!!!

If you look in the Wicks catalog they have a pretty good Rivnut dimension dwg. The major problem with the flush variety is the minimum thickness of the material to accommodate the head (.065 minimum). This is generally thicker than is useful to us. Note Rivnuts are available "keyed" which is a little bump that fits into a tiny recess to resist turning. I personally put them in with a little 5 min epoxy or JB Weld.

Be careful using flush rivnuts. I have never be able to find any of the correct grip length for our thin skins (on the airplane that is). In order to minimize spinning the rivnut must pull down to grip the skin. Keyed rivnuts are a must. File a notch to accept the key. Also epoxy on the rivnuts will help prevent spinning.
