PITCH DIAMETER is at P/2 or 0.500P. MINOR DIAMETER is at P/4 or 0.250P for UN or UNJ is at 5P/16 or .3125P. Thepair 1A and 1B define the loosest fit; 3A and 3B define the tightest. Class 1A/1B threads are used for rough work, for example, where some thread damage can be expected or conditions are very dirty. Class 2A/2B threads are for general use. Class 3A/3B fasteners are used for applications requiring an extra degree of precision. 4- 40 unc 2.35 43 3 - 56 unf 2.15 45 5 - 40 unc 2.65 38 4 - 48 unf 2.40 42 6 - 32 unc 2.85 36 5 - 44 unf 2.70 37 8 - 32 unc 3.50 29 6 - 40 unf 2.95 33 10 - 24 unc 4.00 25 8 - 36 unf 3.50 29 12 - 24 unc 4.65 16 10 - 32 unf 4.10 21 1/4" - 20 unc 5.35 7 12 - 28 unf 4.70 14 5/16" - 18 unc 6.80 f 1/4" - 28 unf 5.50 3 3/8" - 16 unc 8.25 5/16" 5/16
