Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Heavy-Duty Structural Fastening: Designed to meet ASTM A193 B7 and ASTM A194 2H standards, these stud bolts provide high tensile strength and corrosion resistance for critical applications in harsh environments.
  • Multi-Size Adaptability: Available in thread sizes from M6 to M64, accommodating diverse engineering requirements across industries.

Key features

  • 1. ASTM-Certified Durability

    • With ASTM A193 B7 and ASTM A194 2H certified materials, you can ensure compliance with industry standards for high-pressure and high-temperature applications. These bolts and nuts are engineered for critical infrastructure, offering superior mechanical strength compared to non-certified fasteners*.

  • 2. Zinc-Plated Corrosion Resistance

    • With a zinc-plated surface, you can achieve ~30% better corrosion resistance than uncoated steel bolts*, protecting against rust and environmental wear in marine, industrial, or outdoor settings.

  • 3. Precision Thread Design

    • With metric studs featuring a precise 1.25D thread profile, you can secure vibration-resistant connections in heavy machinery or structural assemblies, outperforming bolts with non-standard thread tolerances*.

  • 4. Customizable Thread Sizes

    • With thread sizes ranging from M6 to M64, you can adapt to diverse project requirements, such as small mechanical components or large-scale construction projects, eliminating the need for specialized fasteners*.

  • 5. Versatile Material Options

    • With steel and titanium material choices, you can balance cost efficiency and extreme durability. Titanium variants offer ~40% lighter weight than steel for aerospace or high-stress applications*, while steel provides cost-effective strength for general use.
