What is ASTM A194 Grade 2H / GRADE 2HM Fasteners ?

These fasteners are made up of carbon steel. These are basically used to manufacture nuts which require great tensile strength as well as other threaded fasteners. Both of them have almost the same chemical composition; the only thing that differs is the testing parameters.

The 2H indicated that the fasteners have been subjected to a hundred percent hardness test and have undergone healing procedures. Manganese along with silicon are present in the chemical composition of these alloys. There is also phosphorus, sulfur and carbon present in this alloy’s chemical composition which together constitutes to make the ASTM A194 Grade 2H / GRADE 2HM Fasteners. This makes the fasteners even more stronger and also increases and improves their resistance towards corrosion and the related damages that could likely occur.


ASTM A194 Grade 2H Heavy Hex Nuts are produced from Medium Carbon Alloy Steel, Quenched and Tempered. These A194 Grade 2H nuts are manufactured from Premium Quality Material.

Application Industries

These material are not a single material but the name for a family of corrosion resistant steels. Like many scientific breakthrough the origins of stainless steel lies in a lucky accident. From the smallest part of zipper to the largest building skyscraper, stainless steel is an essential part of modern life.Stainless steel’s strength, resistance to corrosion and low maintenance make it the ideal material for a wide range of applications. It is also has a long life cycle and is 100% recyclable.
