ASTM A194 Grade 2H Nuts Manufacturer & Supplier
ASTM A194 Grade 2H is a standard specification that is applicable to high tensile nuts and other internally threaded fasteners made of heat-treated carbon steel. Grade 2H nuts are usually made by means of hot forging, cold forging or machine work of heat-treated bar stock. ASTM A194 standard outlines the standards needed for chemical composition, heat treatment, hardness, proof load, and other important mechanical properties to guarantee the strength and reliability of Grade 2H fasteners in challenging applications.
