ThreadUTS

ThreadUTS models Unified Thread Standard specifications (UNC/UNF/UNEF) widely used in North America. It records major diameter, threads per inch, series, and class of fit, along with whether the thread is internal or external. The model also stores information about thread length, chamfer requirements, and any notes on plating or locking features. Structured UTS data allows downstream systems to verify compatibility with imperial fasteners, select the right taps and gauges, and maintain traceability when multiple thread standards appear on the same drawing. Confidence metadata enables targeted review of critical fastening interfaces before release and supports conversions to metric equivalents or company-specific specs.

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`
