@spikeyxxx You’re right with avoiding the “Subsurf Modifier” because handling the holding edges so that they don’t distort you the round head rim is difficult if not impossible. So, given that a screws manufacturer would please you to model that screw for a close-up shot, you would simply double to a 40-vertices-circle?
PS: I’m wondering what the special benefits oft the different screw head types are from the overview presented by @spikeyxxx 🤔?
