Technical features of the ASME B 18.2.3.9M standard
This regulatory document defines the current geometric parameters and technical requirements for heavy metric hex bolts included in the American National Standards Institute (ANSI) system of standards. Products compliant with this standard are designed for high-load assemblies where increased strength of the fastening connection is required.
EV Group China experts emphasize that the presence of specifications in the standard does not guarantee the stock availability of every item from all manufacturers. To optimize the procurement process and select fasteners for specific engineering tasks (taking into account the strength class and material), we recommend sending inquiries to EV Group China specialists to clarify current production capabilities and product availability.
