description = """Metric coarse-thread nuts in seven styles, with catalogue sizes as presets. Envelope geometry for \
assemblies: the wrenching shape at its nominal width across flats, the standard's height and a plain bore at the \
nominal thread diameter; the thread is not modelled. Lock nuts are shown as the hexagon over their full height.

The bearing face is on the XY plane at the origin and the nut extends along +Z. Each style has the sizes of its \
standard (see the README for the tables and their sources)."""
