Metric Heavy Duty Hex Nuts

What are Metric Heavy Duty Hex Nuts?

Metric Heavy Duty Hex Nuts are a distinct category of fasteners within the realm of precision engineering, designed to withstand high-load applications. Their defining characteristic is a greater thickness across the faces compared to standard hex nuts, which bolsters the thread engagement and offers enhanced grip, crucial in heavy-duty mechanical and industrial operations. The symmetrical six-sided profile makes these nuts compatible with various tools and also reduces the risk of slippage during high-torque applications.

How Metric Heavy-Duty Hex Nuts Work.

The operative principle of Metric Heavy Duty Hex Nuts involves a longer-than-usual interaction with a mating threaded bolt or stud. The internal threading of the nut aligns with the external threading of the bolt, forming a secure fastening assembly. Upon application of axial load, the extended bearing surface of these nuts distributes the stress over a larger area, mitigating deformation and ensuring a stable connection. The hexagonal form factor offers multiple angles for wrench engagement, facilitating an easy installation and removal process.

What Material Are Metric Heavy-Duty Hex Nuts Made From?.

Embodying resilience and longevity, Metric Heavy Duty Hex Nuts at Accu are manufactured from high-grade stainless steel variants. The A2 Stainless Steel variant offers a blend of mechanical strength and excellent corrosion resistance under standard environmental conditions. For applications in marine environments or where exposure to aggressive corrosives is a concern, we provide an A4 Marine Grade Stainless Steel variant, which features enhanced resistance to chloride-induced corrosion, offering enduring performance in challenging environments.

What Size and Type of Metric Heavy Duty Hex Nuts Are Available?.

Accu offers an extensive size range for Metric Heavy Duty Hex Nuts to cater to multifarious engineering applications. Our offering starts from the more compact M3 (3mm) variant, suitable for precision applications, extending up to the robust M20 (20mm) version for tasks demanding high strength and load-bearing capacity. In addition, we offer related products like Hexagon Full Nuts and Hex Jam Nuts, which can be cross-referenced for applications with distinct design and performance criteria.


Q: How does the design of Metric Heavy Duty Hex Nuts contribute to their functionality?.

A: The bolstered thickness across flats in Metric Heavy Duty Hex Nuts provides more thread engagement that effectively distributes load stress. Additionally, the six-sided profile offers multiple engagement points for wrenches, making these nuts highly versatile and user-friendly in high-torque applications.

Q: Are Metric Heavy Duty Hex Nuts suitable for marine environments?.

A: Yes, especially those made from our A4 Marine Grade Stainless Steel, which offers enhanced corrosion resistance in marine settings and other harsh environments.

Q: What tools do I need to fasten or loosen Metric Heavy Duty Hex Nuts?.

A: Metric Heavy Duty Hex Nuts require a spanner or a socket wrench that matches the nut's size. The six-sided design offers flexibility for tool engagement, making them easy to work with.

Q: How do I choose the correct Metric Heavy Duty Hexagon Nut size for my project?.

A: The correct size is determined by the size of the mating bolt or stud, the material thickness, and the load-bearing requirements of your project. Accu offers sizes ranging from M4 (4mm) to M20 (20mm) to meet your project's precise requirements.

Q: Does Accu have a minimum order quantity for Metric Heavy Duty Hex Nuts?.

A: No, Accu understands the diverse needs of its customers. Therefore, we provide the option to purchase a single unit or place a bulk order for thousands of Metric Heavy Duty Hex Nuts.
