ASTM A194 Grade 2H Nuts

ASME SA 194 Gr 2H Heavy Hex Nut manufacturer and exporter in India

The nominal size of the ASTM A194 2h Nuts ranges from ¼ inches to 4 inches. These products are made as heavy hex nuts and they come in different proof load stresses for plain and galvanized nuts. The A194 2h Coupling Nut comes with 175ksi proof load stress for plain nuts and 150ksi for galvanized nuts. The fasteners in this grade of material are also of high hardness. The hardness of the Sa194-2h Nuts is 248BHN minimum in the Brinell hardness score. As these are heavy tensile nuts, these are used in heavy vibration and high stress applications such as aircraft engine components and in automobile engine components. The ASTM A194 Grade 2h Material is made up of carbon, manganese, phosphorus, sulfur and silicon for all classes. The class 4 has added molybdenum in the composition. The classes 7, 7M, 8 and 8M have added nickel from 8-10%. Class 8 material lacks molybdenum but the class 8M ASTM A194 2h Material all the mentioned elements in the composition, making it the strongest and most expensive class in this grade of material.
