U ser 's GUide — 41Size. If the Thread Size you enter is not a standard size or ifyou have a non-common TPI/Pitch, you will need to directlyenter the TPI/Pitch value, pressing t after entering it in orderto store the Thread Size. Both of these entry methods arecovered in the examples provided within this section.The following specifies the entry ranges that the calculatorallows for the Thread Size and TPI/Pitch values for numeric,fractional and metric Thread Sizes:Thread Size TPI/PitchNumeric 0, 1, 2, 3, 4, 5, 6,8, 10, 12, 14less than 100Fractional 0.06" to 6" less than 100Metric 1 mm to 300 mm less than or equal to 10Note: Entries outside of the ranges mentioned above will result in anEntry Error.The following tables list the available Thread characteristicsprovided by the Thread Size function. Note that there are twoseparate listings, one for Internal Threads and one for ExternalThreads. The listing shown within the Thread Size functionis determined by the set Thread Classification (see ThreadClassification section).Internal ThreadThread Size Minimum Pitch DiameterCut Tap Drill Size* Maximum Pitch DiameterRoll Tap Drill Size* Minimum Minor DiameterClose Fit Drill Size* Maximum Minor DiameterFree Fit Drill Size* Minimum Major Diameter* If the resulting hole size is greater than 2 Inches or 50 mm, the actualhole size will be displayed instead of adjusting to the closest Drill Size.(cont’d)
