The a194 2h material, which in this case is a carbon steel alloy could be further processed by centerless grinding process or by a cold drawing process. Per the specification, the alloy of the ASME SA 194 Gr 2H Heavy Hex Nut is required to conform to the chemical composition that has been prescribed. These astm a194 grade 2h yield strength nuts are subjected to various tests such as hardness tests,  cone proof load test and proof of load test.

The tests performed on the carbon steel based ASTM A194 Grade 2H Hex Nuts are to meet the requirements specified in this standard. Usually, the grade mentioned in the ASTM A194 Gr 2H Hex Head Nuts is indicative of the condition it is to be furnished in. In this instance, the carbon steel grade 2h coupling nuts are to be furnished in a quenched and tempered condition. In order to evenly distribute the load of the fastener, the astm a194 grade 2h washer is used in conjunction with a nut or a bolt.
