  • Where specifying nominal size in decimals, zeros preceding decimal and in the fourth decimal place shall be omitted.
  • Applicable to screw types as indicated by code symbols.
    Type AB thread forming.
    Types B and BP thread forming and Types BF and BT thread cutting.
    Type C thread forming, Appendix; and Types D, F, G, and T thread cutting.
  • No tolerance for gaging diameter is given. If the gaging diameter of the gage used differs from tabulated value, the protrusion will be affected accordingly and the proper protrusion values must be recalculated using the formulas shown in Appendix.
This type of recess consists of two intersecting slots with parallel sides converging to a slightly truncated apex at bottom of recess.
