Types of Fasteners
Bolts
Bolts are essential fasteners used to assemble and secure components in a wide range of industrial applications. They are manufactured in various head styles such as Hex Head, Socket Head, Round Head, Square Head, and more. These bolts are available in different thread types like UNC, UNF, Metric, and BSW, depending on specific engineering requirements.
We offer bolts in materials including Stainless Steel (304, 316, 321, 347, 904L), Carbon Steel (Gr. A, B, C), Alloy Steel (B7, B16, L7), Duplex & Super Duplex Steel (S31803, S32750, S32760), and High Nickel Alloys (Inconel, Monel, Hastelloy, Titanium). These fasteners are widely used in sectors like oil & gas, petrochemical, construction, shipbuilding, power generation, and heavy engineering.
Available in finishes such as plain, zinc-plated, hot-dip galvanized, PTFE-coated, and black oxide, our bolt range complies with international standards like ASTM, DIN, ISO, BS, and IS, ensuring durability, tensile strength, and corrosion resistance in critical applications.

Nuts
Nuts are internally threaded fasteners used in conjunction with bolts, screws, and studs to secure components in various mechanical and structural assemblies. They come in multiple types including Hex Nuts, Lock Nuts, Dome Nuts, Wing Nuts, Nylock Nuts, Flange Nuts, and Cap Nuts, catering to diverse application needs.
Manufactured from a variety of materials such as Stainless Steel (304, 316, 321, 904L), Carbon Steel, Alloy Steel, Duplex & Super Duplex Steel, and High Nickel Alloys like Inconel, Monel, Hastelloy, and Titanium, these nuts ensure reliability and corrosion resistance in critical applications.
Available in thread types like Metric, UNC, UNF, and BSW, our nuts are offered in surface finishes such as zinc-plated, hot-dip galvanized, PTFE-coated, and black oxide. All products conform to international standards including ASTM, DIN, ISO, BS, and IS, making them suitable for use in industries such as oil & gas, petrochemical, chemical, construction, power, and marine.

Studs
Studs are headless threaded fasteners that are used to join two components with nuts on both ends. They provide superior load distribution and are ideal for applications requiring high strength and stability. Common types include Full Threaded Studs, Double-End Studs, Tap-End Studs, and Continuous Thread Studs.
Our studs are manufactured from high-quality materials including Stainless Steel (304, 316, 321, 347, 904L), Carbon Steel (ASTM A193 Gr. B7/B16), Alloy Steel, Duplex & Super Duplex Steel, and High Nickel Alloys such as Inconel, Hastelloy, Monel, and Titanium. These studs are suitable for use in critical environments like refineries, petrochemical plants, offshore platforms, and pressure vessels.
Available in thread types such as UNC, UNF, Metric, and BSW, and surface finishes like black oxide, hot-dip galvanized, PTFE-coated, and zinc-plated, our studs comply with global standards like ASTM, ASME, DIN, ISO, and BS to ensure durability, dimensional accuracy, and corrosion resistance.
