What is IS Fasteners?

IS Fasteners are bolts, screws, nuts and washers manufactured to specifications published by the Bureau of Indian Standards (BIS), India’s national standards body. IS specifications define precise tolerances for thread pitch, head geometry, drive type and material property class, making IS fasteners the mandated benchmark for infrastructure, automotive and industrial projects across India. Sterling Fasteners manufactures the complete IS catalogue — hex bolts, hex nuts, washers and structural fasteners — under a single quality management system, giving buyers one supplier for an entire IS bill of materials. Our production facility runs cold-forging and CNC threading lines dedicated to metric fasteners, supported by an in-house metallurgical lab for batch testing. Whether you need a single IS 1364 size or a mixed container of several IS standards, our export team consolidates documentation, packing lists and mill certificates into one shipment.
