Product Overview
Engineered for extreme environments, our ASTM A320 L7 Steel Stud Bolts deliver unmatched strength, durability, and corrosion resistance for critical applications in low-temperature and high-pressure systems. Customizable in length, diameter, and threading, these zinc-plated stud bolts are precision-manufactured to meet rigorous industrial standards, making them ideal for oil and gas, petrochemical, and marine industries where reliability is non-negotiable.
Key Features
✅ ASTM A320 L7 Compliance
Crafted from alloy steel grade L7, these stud bolts excel in sub-zero temperatures (down to -150°F / -101°C) and high-stress environments, ensuring toughness and impact resistance.
✅ Zinc Plated Finish
Electroplated zinc coating provides superior corrosion protection against moisture, chemicals, and saltwater, extending service life in harsh conditions.
✅ Fully Customizable
Tailor dimensions and specs to your needs:
- Length: 10mm (standard) or custom lengths up to 500mm.
- Diameter: M6–M36 (metric) or UNC/UNF imperial sizes.
- Threading: Full or partial threads, fine/coarse pitch.
✅ High Tensile Strength
Heat-treated to Rockwell C28–32 hardness, with a tensile strength of 150 ksi (1,034 MPa), ensuring resistance to shear, fatigue, and deformation.
✅ Global Certification
Complies with ASTM A320, ASME B16.5, ISO 898-1, and NACE MR0175 for sour service environments.
