Hex Nuts
Hex Nuts are six-sided internally threaded fasteners designed for secure tightening with bolts, studs, and threaded rods. These nuts are widely used in construction, machinery, automotive, aerospace, and heavy engineering industries, providing strong, vibration-resistant connections.
At Rajal Industries, we manufacture precision-engineered Hex Nuts conforming to ISO, ASME, and DIN standards, ensuring superior thread fitment, high load-bearing capacity, and long-term performance.
