I thought of threadlocker--which is a CA--but figured it might be a bit messy 
and with limited surface area--unlike bolt threads--epoxy will bond stronger. 

For that matter, why not use pop rivets? 


I small drip of CA glue is probably as good as anything, and will be easier to 
apply hundreds of time than epoxy would be. 

But the problem here is that the 
end of a brad has very little area for glue to adhere to, so I doubt that any 
glue will greatly increase the strength of a properly-fitting push nut. 

the end of the brad could be mushroomed a bit without damaging anything, that 
might make it more secure.
