Hello,
Shear studs are called connectors in BoM template editor, and in order to have them in lists you need to configure your template to allow the content : Connectors. To do this, you need to right-click on the template name in BoM editor - choose "Report Contents". In this dialog, check : Connectors. You can also see the attached picture for the location of this dialog.
Regards,
Dumitru Berteanu
