OptionalunitThe unit the fastener is made in and its lengths are read in; the size names an inch thread whatever it is.
OptionalframeWhere it sits: the origin where it bears, as under a head, the normal along its axis away from the part. Left out, the ground, facing +Y.
OptionalseriesWhether the thread is coarse (UNC) or fine (UNF), setting a modelled thread's pitch and the tip's chamfer; #0, which has no coarse thread, is cut fine.
OptionallengthThe length of the screw from under its head to its tip, in unit.
OptionalmodelledWhen true the threaded length is modelled, as parts.mechanical.machining.ansi.thread cuts it, its
faces all named thread; when false the thread is a light cosmetic face.
OptionalfullyWhen true the screw is threaded to its head; when false only for the length ASME B18.2.1 gives, leaving a plain shank a modelled thread shows.
