       The fastener on the chevrons is unlike any I've ever seen previously. It is a piece of sheet metal stamped into a hexagonal shape with a hole and one 8-32 thread going through it. I'm guessing, but such a frail piece of metal isn't meant to be tightened very much, thereby protecting the equally frail silver solder joint that holds the stud attached to the chevron.
     So, they don't weigh much and it is no surprise to see chevrons with missing studs.
A good hot soldering iron will help one in eliminating the old solder joint.
