Astm A563 Dh Heavy Hex Nuts Grade A

ASME SA 563 Coupling and hex nut manufacturer, check astm a563 grade a nuts Specification and Equivalent here

ASTM A563 Nuts come under the specification for carbon steel and alloy steel nuts that are intended for general, mechanical and structural applications. Viha Steel & Forging is a manufacturer of the different grades of nuts such as the astm a563 dh heavy hex nuts. The hex nuts are easy to install with tools and therefore it is one of the most commonly used type of nuts.

There are different grades as A, B, C, D, DH, C3 and DH3. The astm a563 hex nuts can come in any of these grades. The different grades specify the carbon steel, weathering steel, quenched and tempered steel, hex and heavy hex types of material and products. Different grades of the astm a563 square nuts also come with different tensile strengths. The sizes range from ¼ inches to 4 inches. The hex nuts range up to 1 ½ inches and the heavy hex nuts range up to 4 inches. The nuts astm a563 grade a have minimum tensile strength up to 90ksi as plain.

When galvanized, the proof load is 68ksi. The hardness of this grade of nuts ranges from 116 to 302 HBN. The DH3 grade has tensile strength up to 175ksi and hardness ranging from 248 to 352 HBN. The astm a563 nuts specifications cover the different mechanical, chemical properties with heat treatments. The chemical composition of these nuts has carbon, manganese, phosphors and sulfur in the composition. The proportions range differently. The A563 Grade A Nut has 0.55% carbon, 0.12% phosphors and 0.15% sulfur. As a leading manufacturer and supplier, we produce the nuts in all types. Please feel free to inquire us on your needs on the different types of nuts such as the ASTM A563m and the respective prices.
