gonna have to second jb weld. I have no direct experience footed carbons however, I have used both adhesives for insert glue on my xx75 and 78's. The problem I have had with gorilla super glue and blunt points like hex heads is that the bond tends to break and drive my point and insert into the shaft effectively destroying it. when I switch to jb weld this was no longer a problem. I have had excellent results with gorilla super glue for fletching my arrows however. These are the only two I am familiar with though and there certainly may be others even better suited to your task as I am not even close to being an expert.
