Shop Heavy Hex Nuts at Fasteners Plus

Heavy hex nuts are essential fasteners designed for high-strength applications, offering reliable performance in both structural and non-structural projects. Their robust construction makes them perfect for use by professionals and DIY enthusiasts alike.

Benefits of Heavy Hex Nuts

• Durability: Built to endure substantial loads and harsh conditions, ensuring long-lasting performance.
• Strength: Provides strong, secure connections vital for heavy-duty applications.
• Versatility: Suitable for a variety of uses, from construction to mechanical applications.

Types of Heavy Hex Nuts:

Heavy hex nuts come in a wide range of sizes, materials, and styles to meet diverse needs and preferences.

• Standard Heavy Hex Nuts: Feature a larger and thicker hexagon shape than regular hex nuts, providing greater strength and resistance to stripping.
• Jam Heavy Hex Nuts: Thinner than standard hex nuts, used when a low-profile fastener is needed, often paired with standard nuts to prevent loosening.
• Locking Heavy Hex Nuts: Designed with a built-in feature to resist loosening under vibration and torque.

Heavy Hex Nut Grades:

Heavy hex nuts are available in various grades and classifications, tailored to specific use cases. Each type of heavy hex nut corresponds to particular grade standards and properties.

• A563 Grade A Heavy Hex Nuts
  • Applications: Suitable for general-purpose structural fastenings, including light to medium-duty construction, machinery assembly, and various DIY projects.
  • Specifications: ASTM A563 Grade A covers the requirements for carbon and alloy steel nuts.
  • Properties: Made from low to medium carbon steel, providing adequate strength and durability for non-critical applications. These nuts are typically not quenched and tempered, offering a balance of cost-effectiveness and performance for general use.
• Grade 2H:
  • Applications: Commonly used in structural applications such as bridges, buildings, and other heavy construction due to its high strength.
  • Specifications: ASTM A194 Grade 2H specifies the requirements for carbon and alloy steel nuts designed for high-pressure and high-temperature service.
  • Properties: Made from medium carbon steel, quenched and tempered, providing high tensile and yield strength.
• Grade DH: 
  • Applications: Utilized where higher strength fasteners are required, such as in heavy construction and steel structures.
  • Specifications: ASTM A563 Grade DH specifies the requirements for heavy hex nuts made from medium carbon steel.
  • Properties: Offers higher strength than Grade 2H, making it suitable for critical structural connections.
• Grade C:
  • Applications: Suitable for general-purpose structural fastenings, including construction machinery and equipment assembly.
  • Specifications: ASTM A563 Grade C covers the requirements for carbon and alloy steel nuts.
  • Properties: Made from medium carbon steel, quenched and tempered, providing a balanced combination of strength and toughness.
• Stainless Steel:
  • Applications: Ideal for harsh environments such as marine, food processing, and chemical industries due to its high corrosion resistance.
  • Specifications: ASTM A194 Grade 8 specifies the requirements for stainless steel nuts, with various grades like 304 and 316 offering different levels of corrosion resistance and mechanical properties.
  • Properties: Known for excellent corrosion resistance, these nuts are suitable for applications where exposure to moisture and corrosive substances is a concern.

Heavy Hex Nut Sizes:

• Diameter: Available in various diameters to suit different bolt sizes and strength requirements. We offer heavy hex nuts from 1/4" to 3/4".
• Height: The height of a heavy hex nut varies based on the application, ensuring proper engagement with the bolt threads for secure fastening.

Frequently Asked Questions About Heavy Hex Nuts:

• What does heavy hex nut mean? A heavy hex nut is a type of fastener with a hexagonal shape. The "heavy" designation indicates that these nuts have larger and thicker dimensions compared to standard hex nuts.
• What is the difference between heavy hex and regular hex? Heavy hex nuts are larger and thicker, providing greater strength, and are preferred for structural and heavy-duty applications. 
• What are heavy hex nuts used for? Heavy hex nuts are used in high-strength fastening applications, often in construction and machinery.

Related Products to Heavy Hex Nuts:

Heavy hex nuts are often used with other fastening components to ensure secure and stable connections.

• Washers: Washers distribute the load over a larger surface area, preventing damage to the material and reducing the risk of the nut embedding into softer materials.
• Bolts: Heavy hex nuts are commonly paired with bolts to create strong, reliable fastenings in structural and mechanical applications.
• Lock Washers: Used with heavy hex nuts to prevent loosening due to vibration and dynamic loads.
