For the screw links, you need to use screw driver to unscrew two pins on any two consecutive links found on either side of your clasp, remove the link once it is completely detached from your bracelet. Slide all the remaining links together to align their pin holes. You should come up with one extra link and an extra pin. Save both in a safe place in case you need them in the future.
