Customized Steel Stud Bolt ZINC Finish With Length 10mm ASTM A320 L7

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.
