ThreadACME

ThreadACME details trapezoidal ACME thread callouts commonly used in power transmission applications. The model records nominal diameter, pitch, thread series, direction, and class, along with flank angle and tolerances when specified. It also links to mating components or notes describing lubrication, backlash requirements, or load direction. Additional metadata tracks whether the thread is stub or general purpose and references applicable standards such as ASME B1.5. By structuring ACME data you can ensure lead screws or jackscrews are manufactured to the correct specification, compatible with off-the-shelf nuts, and supported by appropriate quality checks and inspection criteria. The object also captures confidence so rare thread variants can receive extra scrutiny.

PARAMETER	DESCRIPTION
`reference_id`	Reference ID to identify the object. TYPE: `int`
`label`	A short description of the feature in a human-readable format. TYPE: `str`
`confidence`	Confidence in the feature extraction or interpretation. TYPE: `Confidence \| None`
`quantity`	The number of threads or instances. Must be non-negative. TYPE: `Decimal`
`diameter`	The diameter of the thread, including nominal size and tolerances. TYPE: `Size`
