TAPS ENGINEERING DATA METRIC FORMULAS FORMULA FOR TAP / DRILL SIZES (METRIC) METHOD 1 Drilled Hole Size (mm) = Basic Major Dia. of Thread (mm) Use whole number for % of thread...for 65%, use 65 (not .65). % of Full Thread X mm Pitch 76.98 METHOD 2 Nominal O.D. - (Dbl. Thread Depth X % of Full Thread) = Drilled Hole Size EXAMPLE: To find the hole size for obtaining 75% of thread in a (M6) 6mm x 1.00 tapped hole, follow first column down to 1.00 threads, then across to 75% of thread. This figure (0.9743), when subtracted from 6mm diameter, is 5.0257, which is the required diameter of hole. See equation: M6 - (1.2990 X 75) = (6 - 0.9743) = 5.0257mm To figure whether or not pitch is too coarse for diameter: (Double thread depth) X 3 = x x = the smallest diameter possible for that T.P.I. NOTE: All numbers are shown in millimeters (mm). To convert metric values to inches, divide by 25.4 mm Pitch Double Thread Depth 50% Thread 55% Thread 60% Thread 65% Thread 70% Thread 75% Thread 80% Thread 85% Thread 4.00 5.19630 2.5982 2.8580 3.1178 3.3776 3.6374 3.8972 4.1570 4.4169 3.50 4.54660 2.2733 2.5006 2.7280 2.9553 3.1826 3.4100 3.6373 3.8646 3.00 3.89690 1.9485 2.1433 2.3381 2.5330 2.7278 2.9227 3.1175 3.3124 2.50 3.24760 1.6238 1.7862 1.9486 2.1109 2.2733 2.4357 2.5981 2.7605 2.00 2.59790 1.2990 1.4288 1.5587 1.6886 1.8185 1.9484 2.0783 2.2082 1.75 2.27330 1.1367 1.2503 1.3640 1.4776 1.5913 1.7050 1.8186 1.9323 1.50 1.94870 0.9744 1.0718 1.1692 1.2667 1.3641 1.4615 1.5590 1.6564 1.25 1.62360 0.8118 0.8930 0.9742 1.0553 1.1365 1.2177 1.2989 1.3801 1.00 1.29900 0.6495 0.7145 0.7794 0.8444 0.9093 0.9743 1.0392 1.1042 0.90 1.16870 0.5844 0.6428 0.7012 0.7597 0.8181 0.8765 0.9350 0.9934 0.80 1.03940 0.5197 0.5717 0.6236 0.6756 0.7276 0.7796 0.8315 0.8835 0.75 0.97430 0.4871 0.5359 0.5846 0.6333 0.6820 0.7307 0.7794 0.8282 0.70 0.90930 0.4547 0.5001 0.5456 0.5910 0.6365 0.6820 0.7274 0.7729 0.60 0.77930 0.3897 0.4286 0.4676 0.5065 0.5455 0.5845 0.6234 0.6624 0.50 0.64210 0.3211 0.3532 0.3853 0.4174 0.4495 0.4816 0.5137 0.5458 0.45 0.58470 0.2924 0.3216 0.3508 0.3801 0.4093 0.4385 0.4678 0.4970 0.40 0.51970 0.2599 0.2858 0.3118 0.3378 0.3638 0.3898 0.4158 0.4417 0.35 0.45470 0.2274 0.2501 0.2728 0.2956 0.3183 0.3410 0.3638 0.3865 0.30 0.38960 0.1948 0.2143 0.2338 0.2532 0.2727 0.2922 0.3117 0.3312 0.25 0.32460 0.1663 0.1785 0.1948 0.2110 0.2272 0.2434 0.2597 0.2759 Figures in table show amount to subtract from O.D. of screw to obtain specific percentages of thread.
