I've experimented with lots of adhesives for various applications. Generally,
it's difficult to bond smooth metal to smooth metal with much strength.
However, a two-part epoxy--like JB Weld--would add some strength to the brad
and push nut connection. It might be easier to use one of the putty epoxies,
the kind you slice off a 'stick' and knead to mix and activate. Then, just
stuff it into the push nut and around the brad, or fill the push nut before you
push the brad through--that would add some strength to the connection.

I'm attaching some light metal pieces to
thick leather. Afterwards the backside of the
leather will not be accessible. I'm using a brad
with a push nut. See here:
http://www.mcmaster.com/#push-nuts/=198uxq
it is very small (1/16" shaft on the brad). After
installation, I clip the end of the brad as close to
the Push Nut as possible so that the leather will
be near flat when finished.
Before closing the backside I'm thinking, for extra
security, to add some sort of adhesive. I have
hundreds of these to do, so I'm also looking to
keeping it simple.
My question is: what type of adhesive would best
assure no movement of the Push Nut. I cannot afford to
have it come loose. What I'm effectively trying to
do is lock the Push Nut on the shaft of the brad.
Any suggestions?
