Description
The ANSI B18.2.2 Stainless Steel Heavy Hex Nut is a robust, high-strength hexagonal nut, dimensioned according to American standards, made from a corrosion-resistant stainless steel, and equipped with a feature to prevent self-loosening. It provides superior strength, corrosion resistance, and a locking mechanism to ensure a secure fit, even in environments exposed to vibrations or harsh chemicals. It is available in 304, 316, or 316L stainless steel. This Heavy Hex Nut is commonly used in applications that require a robust and reliable fastening solution. It is particularly suitable for heavy machinery and construction projects , offshore and marine environments , high-stress industrial applications, and chemical processing.
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.
