Optionalsize: isoThreadSizeEnumOptionalpitch: numberOptionallength: numberOptionalinternal: booleanOptionalunit: unitOfLengthEnumOptionalframe: Bit.Inputs.Base.FrameOptionalsizeThe thread size, such as M8; the default is the default screw's and bolt's.
OptionalpitchThe distance from one crest to the next, in millimetres as ISO names it. Left out, the size's coarse pitch.
OptionallengthThe threaded length along the axis, in unit: at most 400 turns of the pitch.
OptionalinternalWhen true, the thread is cut in a hole drilled to the minor diameter, as in a nut; when false, on a shank turned to the nominal.
OptionalunitThe unit the thread is cut in and its length is read in.
OptionalframeWhere the thread starts, at a hole's mouth or under a head, its normal out of the part: the thread runs against it. Left out, the ground, facing +Y.
An ISO metric thread modelled on a shank or in a hole, for
parts.mechanical.machining.iso.threadTool: its size, a fine pitch if wanted, its length, whether it is cut inside a hole and the unit.
