It refers to full threads. A193-B7 indicates the material type. What do W/A194-2H HVY-HEX-NUT UNC-ISO S-FN GR-2AB HEX-DIM=ANSI mean? Could you please explain that?
W/A194-2H HVY-HEX-NUT UNC-ISO S-FN GR-2AB HEX-DIM=ANSI: a coarse-threaded nut made of material 2H
Let’s check the specifications; who can remember them all?
A193 and A194 are the ASME material standards for studs and nuts, respectively. A194-2H denotes grade 2H in the SA194 standard (that is, the material type) ； A193-B7 denotes grade B7 of the material as specified in the SA193 standard (that is, the material type). FULL-THD indicates that the stud is a fully threaded stud. HVY-HEX-NUT refers to a heavy-duty hex nut.
