Overview: Structural Fastener Industry in India
India’s structural fastener industry supports bridges, steel buildings, transmission towers, railways and heavy infrastructure, where high-strength bolts, nuts and washers are critical load-bearing components. BIS standard IS 3757 governs high-strength structural bolts, while IS 6623 covers matching nuts. Demand is reinforced by India’s finished-steel consumption, which reached 163.7 million tonnes in FY2025-26, up 7.6% year on year, alongside sustained infrastructure investment nationwide.
