Ratna Exports specializes in manufacturing ASTM A194 Grade 2H Nuts, available in standard hex or heavy hex configurations. Our product range includes both imperial and metric sized hex nuts, as well as heavy hex nuts. Grade 2H nuts can be customized with various surface coatings such as plain black phosphate, plain zinc, cadmium, or hot dip galvanizing to suit specific requirements. Metric hex nuts adhere to DIN 934, ASME B18.2.4.1M, and B18.2.4.2M standards, while imperial hex nuts are produced according to ASME B18.2.2 Table 4, IS-1363-3, and IS 1364-3 standards. Our imperial-sized heavy hex nuts conform to ASME B18.2.2 Table 10, whereas Metric heavy hex nuts are manufactured as per ASME B18.2.4.6M standard. For your convenience, here’s a summary of the specifications for ASTM A194 Grade 2H Nuts:
- Chemical Composition: ASTM A194 Grade 2H nuts typically contain carbon, manganese, phosphorus, sulfur, silicon, chromium, and molybdenum. The precise composition ensures the desired mechanical properties and corrosion resistance.
- Hardness: Grade 2H nuts are heat-treated to achieve a specified hardness range, typically within the Rockwell C 24 to 35 range. This ensures sufficient strength and toughness for demanding applications.
- Proof Load Requirement: ASTM A194 Grade 2H nuts are designed to meet specific proof load requirements, ensuring they can withstand the intended loads without permanent deformation. The proof load is determined based on the size and thread pitch of the nut.
- Dimensional Standards: Ratna Exports adheres to internationally recognized dimensional standards such as DIN, ASME, and IS for metric and imperial-sized nuts. This ensures compatibility and interchangeability with corresponding bolts and fasteners.
- Surface Coatings: Various surface coatings are available to enhance the corrosion resistance and appearance of Grade 2H nuts. Options include plain black phosphate, plain zinc, cadmium, or hot dip galvanizing, catering to different environmental conditions and application requirements.
