U Bolts Supplier in India - Stainless Steel (304, 304L, 316, 316L), Carbon Steel, Alloy Steel & Duplex

Ananka Group is a U Bolts Manufacturer offering high-quality fasteners made from stainless steel, galvanized steel, carbon steel, and alloy steel. These U-shaped bolts with threaded ends are designed to secure pipes, tubes, and round objects to structural components. Manufactured in accordance with ASTM, BS, and IS standards, U bolts provide excellent holding strength and corrosion resistance. They are widely used in construction, plumbing, marine, agricultural equipment, and industrial support systems where secure clamping is required for curved surfaces. 

We offer proven and guaranteed U bolt solutions tailored for demanding industrial conditions. Through trusted B2B portals, we supply both standard and customized sizes, coatings, thread lengths, and bend diameters to meet project-specific needs. Known for their durability and adaptability, our U bolts are ideal for bulk procurement and are supported by fast, reliable logistics. With easy installation and long-lasting performance, they provide a simple solution for structural and mechanical support applications.

The above U Bolt weight chart and grade table provide a clear and practical reference for selecting the right fastener based on size, strength, and application requirements. The weight chart highlights how variations in diameter, width, and length directly impact the overall mass, which is essential for load calculations and bulk procurement planning. Meanwhile, the grade table covers a wide range of materials such as Stainless Steel 304/316, Carbon Steel, Alloy Steel, and advanced grades like Duplex (2205) and Super Duplex (2507), ensuring suitability across industries from construction and piping to marine and chemical processing. By combining dimensional data with material specifications, these charts help engineers, buyers, and suppliers make informed decisions for durability, corrosion resistance, and performance in different operating conditions.
