However, for a standard screw, the groove geometry is typically defined by the thread diameter ($d$). The standard specifies the length of the incomplete thread and the shape of the point. Sample Deped Anecdotal Record Form Download - 3.79.94.248

Here is a breakdown of what this standard covers, why the "Gola" (groove/notch) matters, and how the data is typically structured. Many engineers search for ISO 4755 expecting a table of dimensions. However, ISO 4755 is a "design rules" standard, not a dimension table itself. It dictates how the groove should be designed to ensure the screw functions correctly.
While "Tabella Gola" translates to "Groove Table," the reference to specifically points to the international standard for "Fasteners — Product design rules for tapping screws and metal drive screws."
