Special tap thread limits are determined by using the formulas shown in Table 331 (USCTI) for Unified Inch Screw Threads and Table 341 (USCTI) for Metric M-Profile Screw Threads. NOTES Tap sizes 0.395” and smaller have an external center on the thread end (may be removed on bottoming taps). Sizes 0.223” and smaller have an external center on the shank end. Sizes 0.224” thru 0.395” have truncated partial cone centers on the shank end (length of cone approx. 1/4 of diameter of shank). Sizes over 0.395” have internal centers on both the thread and shank ends. For standard thread limits and tolerances for Unified Inch Screw Threads see table 327 (USCTI) and for Metric Threads see Table 337 (USCTI). For eccentricity tolerances of tap elements see Table 317 (USCTI). Element Nominal Diameter Range - Inches Over To (Inc.
