ThreadSpecs v2.0 facilitates calculation of characteristics for UN, UNJ. Buttress, Acme, Metric, Metric J, and Whitworth thread forms. It allows users to enter thread size data for real-time determination of dimensions required for manufacture or inspection of standard/special external and internal threads, regardless of diameter/pitch. Thread engineering software also calculates effects of plating and coating on thread dimension data display in inch or metric formats.
