Stud Bolts
High-Strength Fastening for Industrial Applications
Stud bolts are fully threaded rods with nuts on both ends, providing secure and reliable fastening in high-pressure and high-temperature environments. Widely used in flange connections, oil & gas facilities, construction projects, and heavy machinery, our high-tensile stud bolts are available in carbon steel, alloy steel, stainless steel, and duplex grades, ensuring strength, durability, and corrosion resistance.
✅ High-Tensile Strength – Made from carbon steel, stainless steel, or alloy steel for maximum durability.
✅ Variety of Threading Options – Available in fully threaded, double-ended, and tap-end designs.
✅ Corrosion Resistance – Options include zinc plating, hot-dip galvanizing, black oxide, and PTFE coating.
✅ Meets Industry Standards – Manufactured according to ASTM, ASME, DIN, and ISO standards.
✅ Custom Lengths & Coatings – Available in custom sizes, finishes, and materials to suit various environments.

1. What is the difference between a stud bolt and a threaded rod?
A stud bolt is specifically designed for high-strength applications and used with nuts and washers. A threaded rod is a general-purpose fastener that can be cut to size.
2. What are the common grades for stud bolts?
Stud bolts come in ASTM A193 B7, B8, B16, and L7 for high-pressure and high-temperature applications.
3. Do you offer custom sizes and coatings?
Yes! We provide custom lengths, thread pitches, and coatings based on your specific requirements.
4. Can stud bolts be used in corrosive environments?
Yes! Stainless steel, hot-dip galvanized, and PTFE-coated stud bolts offer excellent corrosion resistance.
5. What nuts and washers should I use with stud bolts?
We recommend pairing them with ASTM A194 Grade 2H, 4, or 7 heavy hex nuts and hardened washers for secure fastening.
✔ High-Quality Materials – Manufactured to meet or exceed industry standards.
✔ Custom Fabrication Available – Choose from various lengths, coatings, and thread types.
