Industrial Threaded Rods & Stud Bolts

AK Steel (India) is a premier manufacturer and stockist of high-performance Threaded Rods and Engineering Studs, designed for critical fastening in the oil, gas, and construction sectors. Our product range includes Full Threaded Rods (continuous thread), Stud Bolts for high-pressure flanges, and Tap End Studs for machined engagement. We manufacture these fasteners in a wide spectrum of materials, including Stainless Steel (304, 316), High Tensile Alloy Steel (ASTM A193 B7), and Carbon Steel, ensuring superior load-bearing capacity and corrosion resistance.

Our manufacturing capabilities allow us to produce studs and rods with precise thread geometry, ensuring a perfect interference fit or free-running fit as required. We specialize in Cut-to-Length services, providing custom sizes from M6 to M100. All products are manufactured in strict compliance with DIN 975, DIN 976, and ASTM A193 standards. As an ISO 9001:2015 certified company, we guarantee that every batch is hardness-tested and supplied with EN 10204 3.1 Material Test Certificates (MTC) for full traceability.
