Need tiny clasp pin for TAG Heuer Jumbo

Hi everyone, new here, can anyone point me in the right direction of what to call this part, and how to acquire? To be clear, it is the pin that goes through the end of the bracelet and holds on the hinged clasp. I realize it is probably a universal part, but didn’t know where to ask this question so thought a Tag Heuer forum was a good place (I am usually nerding out on vintage BMWs, but recently added this new money-sucking hobby to my list). I am freshening this Jumbo up with a new bracelet, selling soon. The original pin will no longer hold tight. And before anyone says anything, I do still have the original bracelet! Thanks in advance.
