ASME/ANSI B18.2.3.9M heavy hexagon flange bolt is a metric standard bolt with heavy duty, hexagonal head and flange face. The bolt size ranges from M5 to M20, which represents the size of its thread diameter. The length (b) of the bolt varies according to the requirements, and the heavy design allows the bolt to withstand greater loads and torques. The hexagonal head design is convenient for tightening or loosening with a wrench or screwdriver. The flange face design increases the contact area between the bolt and the connection, improving the stability and sealing of the connection. ASME/ANSI B18.2.3.9M heavy hexagon flange bolt is widely used in various occasions that require high-strength and stable connections, such as mechanical engineering, construction, bridges, vehicles and other fields. This bolt is compatible with multiple standards, such as SAE J1199, ASTM F568M, F738M, F468M, etc.
