Tr8 Flange Nut POM

grabcad

Simple model with key features necessary for assemblies. I didn't model a thread as there is no point to do this if You are not going to manufacture the thread. Main dimensions are accurate for any pitch of trapesoidal Tr8 thread. I share editable FreeCAD model and step file. It is modeled as POM (Polyoxymethylene), but there is no problem to change it to Brass.
