ASTM A453 GR 660 CLASS B Heavy Hex Nuts

ASTM A453 Gr.660 Cl. B Heavy Hex Nuts are large hexagonal nuts designed for use with high-strength bolts and screws. They are made of a material tested for strength and durability to ensure they can handle the load. The grade of these nuts corresponds to the strength of the material used in manufacturing them, which is higher than regular hex nuts. The Class B designation refers to the nut's mechanical properties, specifically its yield strength of 105 ksi minimum.

These ASTM A453 Grade 660 Class B Heavy Hex Nuts can be used for various applications, including structural bolting, bridge construction, pressure vessels, machinery mounting plates, power plants, and more. These fasteners can also be used in automotive and aerospace applications and industrial equipment such as pumps and compressors. These heavy hex nuts are some of the most versatile fasteners in the world. They come in various sizes and materials and are used for everything from construction projects to repair work.

The main benefit of using ASTM A 453 GR 660 Class B Nuts is their superior strength to other fasteners like plain hex nuts or machine screws. This makes them perfect for use on heavy machinery or specialized equipment where reliability is essential. Additionally, they provide excellent corrosion resistance due to their composition, which makes them an ideal choice for marine applications or areas exposed to harsh conditions such as saltwater or extreme temperatures. They also offer ease of installation due to their one-piece design, eliminating the need for costly threading operations during installation. Several types of SS hex nuts are available, like ASTM A 453 GR 660 Class C Heavy Hex Nuts, ASTM A 453 GR 660 Class D Heavy Hex Nuts, etc.

ASTM A453 Gr 660 Class B Lock Nuts are an excellent choice for any application requiring a high-strength fastener with superior corrosion resistance and ease of installation. These versatile fasteners can be used for everything from structural bolting to mounting plates on industrial equipment. We also manufacture other products such as Aluminium Bronze Heavy Hex Nuts, Duplex Steel S32205 Nuts, etc.

The Heavy Hex design provides a larger bearing surface, and the Class B designation ensures that the nuts have excellent mechanical properties, including high yield strength. Compliance with the ASTM A453 specification ensures that these nuts meet rigorous standards for chemical composition, mechanical properties, and dimensional tolerances, ensuring they are safe and reliable for use in critical applications.
