Description
The Stainless Steel Heavy Hex Nut is a robust, high-strength fastener manufactured in accordance with the ANSI B18.2.2 standard. Designed with a larger width across flats and increased thickness compared to standard hex nuts, this Heavy Hex Nut provides superior load-bearing capacity and enhanced resistance to vibration and loosening.
Available in 304, 316, and 316L stainless steel, this nut delivers excellent corrosion resistance, mechanical strength, and a locking mechanism, making it ideal for demanding applications in construction, heavy machinery, offshore and marine environments, chemical processing, and other high-stress industrial sectors.
Features & Benefits
- High-Strength Material: Made from high-quality stainless steel, the nut offers superior strength and high hardness, with no deformation. It also has high wear resistance, strong oxidation resistance, and will not rust in humid environments.
- Corrosion and Wear Resistance: Built to withstand exposure to moisture, chemicals, and extreme temperatures, this heavy hex nut is perfect for marine, industrial, and offshore applications.
- Strong Locking Mechanism: The nut’s design helps prevent self-loosening, even under high vibrations or stress, providing a secure and reliable fastening solution.
- Standardized Hexagonal Design: Meets the ANSI B18.2.2 standard, ensuring compatibility with other fastening components and tools. The hexagonal shape allows easy installation and removal.

FAQ:
Q1: What is the difference between a standard hex nut and a Heavy Hex Nut?
A: A Heavy Hex Nut is slightly larger and thicker than a standard nut, providing more thread engagement and a greater bearing surface for high-strength, heavy-duty applications.
Q2: Which material grade should I choose: 304, 316, or 316L?
A: Use 304 for general-purpose corrosion resistance. 316 offers superior protection against chlorides and marine environments. 316L (low carbon) is preferred for applications involving welding to prevent sensitization and maintain maximum corrosion resistance.
Q3: Is this nut suitable for high-vibration applications?
Yes. The heavy hex design enhances stability and reduces the risk of self-loosening under vibration or dynamic loads.
Q4: Does this nut require a separate locking washer?
A: While it is designed to resist self-loosening through its robust ANSI B18.2.2 geometry and high-friction fit, extreme vibration scenarios may still benefit from supplemental locking devices depending on the specific engineering requirements.
Q5: What bolts are compatible with this heavy hex nut?
It is compatible with UNC and UNF threaded bolts and rods that meet corresponding ANSI standards.
