I've been given some 'Cherry' rivets from a friends hanger clear-out, and
I'm amazed to see that they have a use by date !!! - not having used any of
these rivets before, is this usual, and how significant is the date.
If you keep them bagged and clean, I do not see any problem using them. I dont think the effect would be like drinking milk way past the expiration date.
If in doubt, shoot one or two rivets into a piece of scrap metal before going any farther
