The nominal gross area Ag corresponds to the cross-sectional area of the unthreaded part of the bolt: The tensile stress area As corresponds to the reduced cross-sectional area inside the threaded part of the bolt. Therefore the mean diameter dm is approximately: Strength properties for bolt steel according to EN 1993-1-8 Table 3.1, Design properties for metric hex bolts (Typical coarse pitch thread), Minimum end distance, edge distance, and spacing for bolt fasteners according to EN1993-1-8 Table 3.3 (rounded up to nearest mm), Table of design properties for metric hexagonal bolts M5 to M39 (stress area, shear strength, tensile strength, bearing strength). Additionally, the minimum strength of grade 8 bolts is approximately 130,000 psi, whereas the maximum strength of stainless steel is not greater than 90,000 psi. This chart helps to identify the grades of bolts using the identification marks on the bolt's head along with the strength and hardness of common grade bolts. Bolts must be tightened using the correct torque. To calculate tensile strength of a bolt, the tensile stress area should be multiplied by 150,000 psi. Grade 8. The shear capacity given in the tables must be reduced for large packings, large grip lengths, kidney shaped slots or long joints when applicable. Smaller diameter grade 8 bolts are cold headed from long spools of wire, where larger bolts are hot forged from billets. The shear strength of a grade 8 bolt is 90,000 psi, assuming the bolt is between 1/4 inch to 1 inch. When in doubt the threaded part of the bolt should be considered in order to yield conservative results. Engineering ANSI Hardware Design Data, See Explanatory notes given below table.
