Hex head hardware bolts from ASME, ISO, and others address bolts, their quality and construction, and their different forms. A popular standard listed here is ASME B18.2.3.5M for metric hex bolts, which covers the general and dimensional data for metric hex bolts recognized as American National Standard. These hex head bolt standards have been recognized worldwide across hardware manufacturing and construction bodies alike. Find the standard that can best help your practice here
This Standard covers the general and dimensional data for metric hex bolts recognized as American National Standard. The inclusion of dimensional data in this Standard is not intended to imply that all of the sizes in conjunction with the various options described herein are stock production items. Consumers are requested to consult with manufacturers concerning lists of stock production hex bolts. Hex bolts purchased for Government use shall conform to this standard, and additionally to the requirements of Appendix III.

ISO 15071:2011 specifies the characteristics of hexagon bolts with flange, small series, of product grade A, with threads from M5 up to and including M16, and property classes 8.8, 9.8, 10.9 and A2 70.
ISO 15072:2012 specifies the characteristics of hexagon bolts with flange with metric fine pitch thread, small series, with product grade A, and with nominal thread diameters from 8 mm up to and including 16 mm and property classes 8.8, 9.8, 10.9, 12.9 or 12.9 (underlined) and A2 70.
This document specifies the characteristics of hexagon head bolts, in steel and stainless steel, with metric coarse pitch threads M1,6 to M64, and with product grades A and B. If in certain cases other specifications are requested, property classes and stainless steel grades can be selected from ISO 898-1 or ISO 3506-1, and dimensional options from ISO 888 or ISO 4753.
This document specifies the characteristics of hexagon head bolts, in steel, with metric coarse pitch threads M5 to M64, and with product grade C. If in certain cases other specifications are requested, property classes can be selected from ISO 898-1 and dimensional options from ISO 888 or ISO 4753.
ISO 4162:2012 specifies the characteristics of hexagon bolts with flanges, small series, of product grade A (except the driving feature which is according to product grade B), with threads from M5 up to and including M16, and property classes 8.8 to 10.9 and A2 70. If, in special cases, specifications other than those listed in ISO 4162:2012 are required, they can be selected from existing International Standards, for example ISO 261, ISO 888, ISO 898 1, ISO 965 2 and ISO 3506-1.
This document specifies the characteristics of hexagon head bolts, in steel and stainless steel, with metric fine pitch threads M8×1 to M64×4, and with product grades A and B. If in certain cases other specifications are requested, property classes and stainless steel grades can be selected from ISO 898-1 or ISO 3506-1, and dimensional options from ISO 888 or ISO 4753.
This International Standard specifies the dimensions of reduced bihexagonal head bolts, with normal or pitch diameter shank and long length MJ threads, in metallic material, coated or uncoated, of strength classes less than or equal to 1 275 MPa. This International Standard is applicable for the compilation of aerospace product standards.
This document specifies the dimensions of normal bihexagonal head bolts, with close or large tolerance normal shank and short or medium length MJ threads, in metallic material, coated or uncoated, with strength classes less than or equal to 1 100 MPa. This document is applicable to the compilation of aerospace product standards.
ISO 3186:2008 specifies the dimensions of large bihexagonal head bolts, with close or large tolerance normal shank and short or medium length MJ threads, in metallic material, coated or uncoated, with strength classes 1 250 MPa to 1 800 MPa. ISO 3186:2008 is applicable to the compilation of aerospace product standards.
ISO 3193:2008 specifies the dimensions of normal hexagonal head bolts, with close or large tolerance normal shank and short or medium length MJ threads, in metallic material, coated or uncoated, with strength classes less than or equal to 1 100 MPa. ISO 3193:2008 is applicable to the compilation of aerospace product standards.
