Rinku Fasteners, a well-respected manufacturer and supplier located in Kolkata, India, specializes in crafting high-quality Stainless Steel 416 Stud Bolts that are built for reliability, strength, and long-lasting performance. Thanks to their state-of-the-art manufacturing facilities and rigorous quality control measures, every stud bolt produced meets international standards for durability and precision. Made from free-machining martensitic stainless steel, Rinku’s SS 416 Stud Bolts provide excellent machinability along with robust mechanical properties. These bolts are perfect for applications that demand outstanding wear resistance, moderate corrosion protection, and consistent performance in engineering, mechanical, and industrial settings.
Stainless Steel 416 Stud Bolts are made up of 12–14% chromium, at least 0.15% carbon, and 0.15–0.35% sulfur to boost machinability. They also contain manganese, silicon, and small amounts of phosphorus and sulfur. As a martensitic stainless steel grade, SS 416 is known for its excellent machinability, solid mechanical strength, and moderate resistance to corrosion. After undergoing heat treatment, these stud bolts achieve impressive tensile strength, good wear resistance, and hardness levels reaching 35–40 HRC. Their stability and durability make them a great choice for medium-stress mechanical applications.
