I'm trying to the the 4-40 sullivan gold clevis on a standard 4-40 pushrod but it seems to be very loose. It is the right threads but it threads on and off so easily and the result it a bit of slop. DOes anyone else use these and if so how do you tighten it up? I don't really want to put a drop of glue on it and I've tried to crimp it a bit but that doesn't work either....

Thx
