OptionalunitThe unit the fastener is made in and its lengths are read in; the size names a metric 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.
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.iso.thread cuts it, its
faces all named thread; when false the thread is a light cosmetic face.
OptionalfullyWhen true the bolt is threaded to its head (ISO 4017); when false only for the length ISO 4014 gives, leaving a plain shank a modelled thread shows.
An ISO hexagon head bolt for
parts.mechanical.fasteners.iso.hexBoltand its twin with face roles: threaded to the head after ISO 4017, or only part of its length after ISO 4014.
