Based in Chennai, India, Vinit Stainless is a reputable producer and supplier of high-performance stainless steel products that are suited for a range of industrial applications. The company provides high-end fastener solutions, such as Stainless Steel 440C Bolts, with a strong emphasis on quality, longevity, and customer satisfaction. These bolts are designed for uses requiring high levels of strength, hardness, and resistance to wear. They function well in high-stress and high-wear situations because of their high carbon content. Performance-driven design, affordable prices, and prompt delivery are all combined at Vinit Stainless to give our clients dependable, long-lasting products that can withstand even the most demanding settings.
The high carbon martensitic stainless steel used to make 440C stainless steel bolts is made up of roughly 16–18% chromium and 0.95–1.20% carbon, with trace amounts of silicon, manganese, and molybdenum. Due to its heat-treatable nature, this alloy exhibits exceptional mechanical strength and wear resistance, reaching Rockwell hardness levels of up to 60 HRC. High durability is ensured by the bolts’ tensile strengths, which surpass 750 MPa. High-stress applications needing superior hardness and edge retention can benefit from 440C’s exceptional performance in dry and mildly corrosive environments, despite its moderate corrosion resistance when compared to austenitic grades.

Stainless steel 440C bolts are very strong, high strength fasteners with excellent damage resistance. They offer moderate corrosion resistance and are ideal for high stress and high damage applications in industrial and industrial applications.
Custom Stainless Steel 440C Hex Bolt is a high-strength fastener with a square head, specifically designed to fit. It provides exceptional strength, wear resistance and durability for tough applications.
Stainless Steel 440C Leg Bolt is a high-strength, corrosion-resistant fastener with a long threaded shaft and flat head, designed for more demanding applications requiring durability and abrasion resistance
Stainless Steel 440C Expansion Anchor Bolt is a high-strength fastener designed to secure concrete or masonry products. It expands in the hole as it tightens, creating a reliably stable surface.
Stainless Steel 440C Hex Flange Head Bolt features a hexagonal head with an integrated flange for increased weight distribution. Provides superior strength and wear resistance for complex industrial applications.
Stainless Steel 440C Full Threaded Bolts have threads along their entire length, providing consistent clamping force and high hardness. They are ideal for high-stress applications requiring strength and wear resistance.
Every Stainless Steel 440C bolt is packaged using high-quality material for protection from damage, rust, or defects during shipping. We focus on the satisfaction of customers by ensuring prompt delivery through effective transportation methods. In addition all relevant documentation related to the product including certificates of Quality are provided to clients. at the time of delivery. Assuring them of the product’s compliance with the highest industry standards. At every step we maintain a commitment to quality and reliable service.
Industrial applications requiring high strength, resistance to wear, and dimensional stability frequently use SS 440C bolts. For applications involving high friction or mechanical stress, such as precision machinery, tooling equipment, and automotive components, their hardness and edge retention make them perfect. These bolts are frequently found in military-grade hardware, aerospace components, pump assemblies, and valves. They are also appropriate for manufacturing, oil and gas, and construction equipment due to their ability to function in high-pressure and high-stress settings. In harsh operating conditions, their long service life is guaranteed by their resistance to mechanical wear.
