Difference between ASTM A194 Grades 2H and 2HM

What makes 2HM different from 2H? Does the M stands for ‘Metric’? Although in many cases ‘M’ stands for Metric, in this case it is not so. Nuts of Grade 2H indicate that the alloy steel used for nut is quenched and tempered whereas in case of Grade 2HM the nuts are additionally tested 100% for hardness. Both these nuts can be manufactured by means of any of the processes - hot forging, cold forging or machining but the material must be heat treated. 2H heavy hex nuts are used in high temperature and high pressure services, with adequate strength and engineering to withstand extreme conditions. 2HM nuts are also produced in a similar way, yet have low proof load values and hardness. So, while 2H nuts can be substituted for 2HM but vice versa may not be true. The similarities and differences in these two grades are: Chemical composition of both grades 2H and 2HM is same.

Industrial Fasteners - Studs, Bolts Nuts - Standards

FASTENER A fastener is a mechanical device for holding two or more bodies in definite positions with respect to each other Most industrial fasteners are covered by two basic standards: one for materials and properties; the other, for dimensions and tolerances. Specifications for materials and properties are published primarily by the American Society for Testing and Materials (ASTM), with some other groups also publishing such standards for specific industry; like  Society of Automotive Engineers (SAE), American Petroleum Institute (API). Standards for dimensions and tolerances are issued primarily by the American National Standards Institute (ANSI) in cooperation with the American Society of Mechanical Engineers (ASME) and the Industrial Fasteners Institute (IFI). At NUBOTECK, ASTM standard with stricter control as defined by API is followed for material and its properties. For size, dimensions and tolerances NUBOTECK follows ASME standards. With compliance to these...
