High-Precision Threaded Rods & Threaded Bars
Stud Bolt India is an ISO-certified manufacturer and global supplier of full-threaded rods, half-threaded rods, and custom metric/imperial threaded studs based in Mumbai, India.
Our engineered threaded bars are thread-rolled under strict precision control to meet ASME, DIN (DIN 975, DIN 976), ISO, and BS specifications. Designed for heavy-duty structural anchoring, pressure vessel flanging, marine hardware, and high-temperature power piping, every threaded rod delivers uniform pitch, precise mechanical properties, and maximum tensile strength.
- Full Mill Traceability (EN 10204 3.1)
- Thread Rolling for Superior Fatigue Resistance
- ASTM A193 B7, B16, SS 304/316, Duplex & Monel
- Metric (M6–M100) & Imperial (1/4" to 4") Sizes
Product Classification
Types of Threaded Rods We Manufacture
Engineered for critical industrial applications, our threaded rods are available in continuous full-thread, double-ended half-thread, and custom thread pitch configurations.
Half Threaded Rods
Features an unthreaded un-worked shank providing superior shear strength, making it ideal for alignment applications and high-shear mechanical joints.
Partially Threaded Rods
Custom threaded ends tailored for targeted grip applications, foundation bolts, equipment anchor assemblies, and specialized structural connections.
Metric & ACME Threaded Rods
Precision metric pitch (M6 to M100) and trapezoidal ACME thread profiles built for heavy linear motion, jacks, and high-load mechanical drive systems.

Export Quality Assurance
Seaworthy Packaging & Quality Controls
Protecting thread integrity during international ocean transit is central to our quality management system.
Every threaded rod manufactured at Stud Bolt India undergoes visual inspection, thread ring gauge verification, and ultrasonic testing where mandated. Export shipments are treated with anti-rust oil, wrapped in moisture-resistant plastic, and bundled into reinforced wooden crates or fumigated ISPM-15 cases.
Fumigated Wooden Crates
ISPM-15 compliant wooden boxes for international shipping protection.
Anti-Corrosion Wraps
VCI paper and shrink wrapping to prevent rust in marine air.
