I have made many pieces using screws to hold parts together. I work
mainly in 18k and platinum. I do not know of a manufacturer that can
supply karat gold screws. I always make my own. Most of the screws
that are commercially available are made of brass. If this will work,
you can try your local hobby shop, model train emporium, or contact
Small Parts in Miami: 800 220-4242. They have a large selection in
various shapes, sizes , and pitches. You will also need to get the
proper size tap to match the screws.
The gold screws used to assemble gold watches are made by the watch
manufacturer. If you plan to make your own screws, you need to
consider the alloy you will use, as well as the size and pitch of
the screws. A soft alloy with a fine thread is easily stripped out
when stressed. Nickle white golds work best, but you can make a hard
enough alloy to use for screws even in 18k.
