description = """ASME B18.3 flat countersunk head socket cap screw (82 degree head), Unified inch threads #0-80 to 1/2-20. Envelope \
geometry for assemblies: countersunk head (A, theoretical sharp), 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 top face is on the XY plane at the origin and the screw points along -Z; `length` is the nominal \
overall length, in inches (the model itself is in millimetres). Dimensions from ASME B18.3 flat head table (see the README)."""
