UNC thread automatic model generator
grabcad
As I struggled to locate specific UNC screw designs, and SolidWorks Toolbox only offered "schematic" threads in its library parts, I decided to practice using equations and create a customizable "stock" thread model. It requires three inputs: "Definition," "TPI," and "Length." After referencing the Unified Thread Standard table on Wikipedia for guidance, this feature is generated; however, it still needs refinement, as it doesn't work with 1" diameter screws yet but serves as a good starting point.
