This document provides available tensile capacity data for various sizes of HV-bolts according to European and German standards. It lists bolt diameters in both metric and imperial units along with the corresponding bolt shank cross-sectional areas. Minimum tensile strengths for the bolts are also specified. Tables show the allowable tensile capacities of the bolts under Allowable Stress Design (ASD) and Load and Resistance Factor Design (LRFD) methods compared to standard A490 bolt capacities. Bolt diameters range from M12 to M64 (5/8 inch to 4-7/8 inches).
