- Where specifying nominal size in decimals, zeros preceding the decimal and in the fourth decimal place shall be omitted.
- Tabulated values were determined from the formula for maximum H
- No tolerance for gaging diameter is given. If the gaging diameter of the gage used differs from the tabulated value, the protrusion will be affected accordingly, and the proper protrusion values shall be recalculated using the formulas shown in Appendix.
