ASME B18.31.4M Threaded Rods covers the complete general and
dimensional data for metric series threaded rod recognized
as an American National Standard. ASME B18.31.4MThis Standard is
applicable to both fine and coarse metric series threads
of diameters from M1.6 to M56.
The inclusion of dimensional data in ASME B18.31.4M Standard is
not intended to imply that all of the products described
herein are stock production sizes. Consumers should
consult with suppliers concerning lists of stock production sizes.
The Tables measurements are also converted into millimeters to make the information clearer and easier to
understand.
