Remarks
1.Figures written by thick letters show the value of Semifinished Hexagon Nut in accordance with old ANSI Standard
2.The above value is calculated on the assumption that the specific gravity of carbon steel is 7.83gm/c.c.(0.283lb/cu-in).Type 304 and 410,multiply the above figures with 1.011 and 0.989 respectively.
