SS 316 nuts offer enhanced protection against chlorides and chemicals, making them suitable for marine and chemical environments. SS 304L nuts have reduced carbon content, improving weldability and resistance to intergranular corrosion, while SS 304H nuts are designed for high-temperature applications.

In addition to these, we offer a range of stainless steel nut bolts and stainless steel cap nuts, available in various sizes and dimensions. Our stainless wing nuts are specifically used in offshore and shipbuilding industries due to their robust performance in harsh conditions. We also provide stainless steel hex heads, which are essential for securing structural components and are produced with meticulous attention to detail.

The incorporation of elements like titanium in our 304 stainless steel nuts ensures exceptional resistance to intergranular corrosion. 321 stainless steel nuts and 316 stainless steel nuts are fortified with molybdenum, enhancing their resistance to chlorides and industrial chemicals. 317 stainless steel nuts are noted for their stability at elevated temperatures.

At Sumit Impex, we adhere to international standards such as ASTM, ASME, DIN, and EN, ensuring that our products meet the highest quality and performance criteria. Each batch of our stainless steel nuts undergoes rigorous testing, including tensile testing, impact testing, hardness testing, and intergranular corrosion testing (IGC), to guarantee exceptional quality.

Our stainless steel nuts are available in various finishes, including bright annealed, powder coating, anodizing, and custom painting, to enhance their functionality and appearance. With competitive pricing ranging from ₹150 to ₹300 per kg in India, we offer excellent value for all your fastening needs.
