I use em all the time and here's a thread I started which should point you in the right direction. One of the links has a source of the 5/32" size you seek.Does anybody know of a source for transfer pins that are in a shape of a NAS1097 reduced head rivet (Oops rivet) or a standard flush rivet? It's not for a RV project, but still needed. Google has not revealed anything, figure this is the best place to ask for help.
Thanks
