Wish there were a threaded post and large screw-on nut
available in sterling. What does everyone else do?
I work mostly in gold, but when I need them, I’ve sometimes
punched out a thin disk with a disc cutter, drilled a center
hole and soldered it to an existing screw back. That’s the
"quick fix" way.
Or, of course, you can always make your own screw back findings
in any size you need. You don’t need to make them look like the
commercial stamped ones. A slightly dapped disk with a bit of
tube soldered to it, drilled through and threaded to fit the
post, and with maybe a wire loop as a "handle, like on the
commercial ones, isn’t all that hard to make, and can look much
more custom than cummercial findings. Another one I’ve done is
to shallowly dap up two disks, so soldered together they end up
like a lentil bead (the flat , flying saucer shaped beads) .
Drill the center through, insert and solder a tube, and thread
it. The result is a very clean looking large threaded nut that
also has some weight to it, which helps balance the earring’s
