I am working on configuring the toolbox in SW2015, SP2.1. There is no provision for a round head Self tapping screw(STS). Was this intentional? if so, how would one go about adding a Round Head STS to the toolbox? I have copied and added regular screws in a toolbox, but I don't know how I would go about (for instance) copying a pan head STS and making it a round head STS. any feedback, help or insight is appreciated. Thanks.
