As a trusted Stainless Steel Hex Bolts Manufacturer in India, we produce a wide range of bolts, nuts, and fasteners in various materials, dimensions, and standards to cater to diverse industrial needs. Our offerings include materials such as SS 304, SS 316, and other austenitic stainless steel grades. Products like the A2 70 Hex Head Bolt are specifically designed for specific applications and services, ensuring reliability and performance.
We provide an extensive range of hex bolts, including Black Hex Bolts and Grade 8 Hex Bolts, available at competitive prices in India. Our Galvanized Hex Bolts are also stocked and ready for immediate supply. The SS 304 Hex Bolt is among the most widely used products due to its robust torque strength and composition of chromium and nickel. For enhanced corrosion resistance, the SS 316 Hex Bolt with added molybdenum is highly preferred. Bolts are manufactured in various lengths, from 1 inch to 24 inches, and diameters, ranging from ½ inch to 2 ½ inches, making them suitable for diverse applications such as heavy load-bearing or specific fitting requirements.
Our products adhere to international standards such as DIN 933 and DIN 931, ensuring universal measurement and consistency in quality. The threading, head styles, lengths, and dimensions of our bolts are designed to meet specific industrial needs. Specialized fasteners such as Hex Flange Bolts and Hex Fittings Bolts are available to suit connection types for fittings and flanges. Additionally, products like the Hex Bolt ISO 4014 are manufactured to maintain global benchmarks for quality and precision.
