ASME B18.2.2 Heavy Hex Nuts – Engineered for Strength and Durability
Heavy-duty applications demand reliable and high-strength fastening solutions, and that’s exactly what ASME B18.2.2 heavy hex nuts deliver. Manufactured to meet strict ASME specifications, these industrial hex nuts offer superior load-bearing capabilities and long-term performance in even the most demanding environments.
At Bigboltnut, we specialize in the production and export of ASME B18.2.2-compliant heavy hex nuts in a wide range of sizes and materials to meet global industrial standards. Whether you're working on infrastructure projects, machinery, or structural frameworks, our nuts ensure secure, high-strength connections.
The ASME B18.2.2 standard defines the dimensional and mechanical properties for hex nuts used in structural and industrial applications. These nuts feature a heavier, thicker profile compared to standard hex nuts, allowing for improved grip, increased contact surface, and better load distribution. ASME B18.2.2 is widely recognized and often used interchangeably with the ANSI standard for industrial hex nuts.
Available Sizes: Metric & Inch
ASME B18.2.2 heavy hex nuts are manufactured in both metric (MM) and imperial (inch) units. Their enhanced geometry makes them ideal for high-performance fastening systems that require durability, strength, and consistency.
Grades & Material Options
Selecting the right grade of heavy hex nut is crucial for performance and longevity. We offer a variety of material and grade options to suit specific applications:
ASTM A563 (Grades A, B, C, DH) – For general and high-strength applications
ASTM A194 (Grades 2H, 2HM, 4, 7, 8, 8M) – Ideal for high-temperature and high-pressure environments
Carbon & Alloy Steel – Preferred in structural and industrial settings
Stainless Steel (A2, A4) – Provides excellent corrosion resistance, perfect for marine and chemical industries
International Standards Equivalents
ASME B18.2.2 heavy hex nuts are compatible with several international standards, enabling their use in projects worldwide. Common equivalents include:
ISO 4032 / DIN 934 – European standard
JIS B1181 – Japanese standard
BS 1768 – British standard
These global equivalents make our heavy hex nuts a reliable choice for cross-border engineering and construction requirements.
Heavy hex nuts are trusted in sectors where strength and safety are non-negotiable. Typical applications include:
Construction & Infrastructure – Used in bridges, highways, and steel frameworks
Heavy Equipment & Machinery – Ensures durable fastening in mechanical systems
