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: 
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?
