NOTE: Thread length l is based on a length of 12 pitches of the UNC thread series. Thread length “l” is a minimum value and has no tolerance. When thread length “l” is added to neck length “l1”, the total shall be no less than the minimum USCTI Table 302 thread length “l”. Unless otherwise specified, all tolerances are in accordance with USCTI Table 302. For eccentricity tolerances, see USCTI Table 317. Table 302 is provided for reference only. WIDIA-GTD™ tap dimensions may differ.
