description = """ASME B18.3 hexagon socket head cap screw (1960 series), Unified inch threads #0-80 to 1/2-20. Envelope \
geometry for assemblies: head (A max, H max), hexagon socket (J, T min) and a plain shank at the ASME B1.1 basic major \
diameter; the thread itself is not modelled.

The head's bearing face is on the XY plane at the origin and the shank points along -Z; `length` is the nominal \
length under the head, in inches (the model itself is in millimetres). Dimensions from ASME B18.3 Table 1 (see the README)."""
