Our hex bolts stand out in the market due to their robust design and premium material properties. Below are the core features that make them indispensable for industrial use.
Corrosion Resistance: Made from top-tier alloys like Hastelloy C276 and Incoloy 825, our bolts resist rust, acid, and saltwater damage, making them ideal for harsh marine, chemical processing, and mining environments.
High Tensile Strength: Available in grades such as Class 10.9 and Grade 8, these bolts can withstand heavy loads and extreme mechanical stress, ensuring structural stability in critical projects.
Temperature Tolerance: The selected alloys exhibit excellent performance in both high and low-temperature conditions, suitable for applications involving extreme thermal fluctuations.
Diverse Finishing Options: We offer multiple surface treatments including Zinc Plated, Hot Dip Galvanized, Dacromet, Nickel Plated, and Black Oxide, enhancing the bolts’ longevity and adaptability to different working environments.
Accurate Thread Design: The coarse and fine thread options are precisely machined to ensure secure and tight connections, preventing loosening even under vibration and dynamic load conditions.
Compliance with Strict Standards: Every batch of bolts is manufactured in accordance with international industry standards, guaranteeing uniform quality and interchangeability with other components.
Thanks to their outstanding performance characteristics, our Super Duplex Incoloy Hastelloy Hex Bolts are widely used in multiple industries:
Heavy Industry: Applied in the assembly and maintenance of large-scale machinery and equipment, providing reliable fastening solutions for high-load components.
Mining Sector: Resistant to corrosion and wear, these bolts are suitable for mining machinery and equipment operating in harsh underground and outdoor environments.
Structural Steel Projects: Used in the construction of steel structures such as bridges, stadiums, and high-rise buildings, ensuring the stability and safety of the overall structure.
General Industry: Ideal for various general manufacturing and repair work, meeting the diverse fastening needs of different production lines.
At PARK, we understand that different projects have unique requirements, so we provide comprehensive custom services to meet your specific needs:
Customized Material Selection: We can produce bolts using special alloys according to your project’s environmental and performance requirements, such as customized Inconel or Hastelloy variants.
Tailored Size & Thread: Whether you need non-standard sizes beyond the M6-M150 range or special thread specifications, our professional team can customize them precisely.
Custom Finishing & Packaging: We offer personalized surface treatment solutions and can arrange packaging according to your requirements, ensuring the bolts are well-protected during transportation and storage.
OEM/ODM Support: We welcome OEM and ODM orders, working closely with you to develop fasteners that perfectly match your product designs and application scenarios.
Our hex bolts strictly adhere to international standards including DIN, ASME, ANSI, and ISO, ensuring compatibility and performance across global markets.
For standard specifications, we have sufficient stock, and the delivery can be arranged within 3-7 working days after order confirmation. For custom orders, the delivery time depends on the complexity of the requirements, usually ranging from 15 to 30 working days.
Every batch of bolts undergoes strict quality inspection, including material composition analysis, tensile strength testing, and corrosion resistance testing, to ensure that each product meets the specified standards before leaving the factory.
Yes, we can provide free samples of standard Super Duplex Incoloy Hastelloy Hex Bolts for your testing and evaluation. You only need to bear the shipping cost. For custom samples, a reasonable sample fee will be charged, which can be refunded when you place a formal order in large quantities.
