Nuts are essential fasteners used in various industries, from automotive to construction. Among the many types available, Heavy Nuts and Flange Nuts are widely used due to their unique structural advantages.
ASTMA194/A563 Carbon Steel Heavy Duty Nuts
Heavy Nuts, also known as thick hex nuts, are designed for high-stress environments where standard nuts may fail. Their thicker construction provides greater load distribution and resistance to vibration loosening.
Key Features of Heavy Nuts:
Material: Typically made from carbon steel, stainless steel, or alloy steel.
Thread Type: Coarse or fine threads depending on application.
Strength Grade: Common grades include Grade 8 (SAE) and Grade 10 (Metric).
Applications: Used in heavy machinery, structural steel connections, and high-tension bolting.
Feature | Heavy Nut | Standard Nut |
---|---|---|
Thickness | 1.5x thicker | Standard thickness |
Tensile Strength | Up to 150,000 psi | ~120,000 psi |
Vibration Resistance | High | Moderate |
Flange Nuts feature a built-in washer-like flange that distributes pressure and prevents loosening under dynamic loads. They are commonly used in automotive and aerospace applications.
Key Features of Flange Nuts:
Material: Often made from stainless steel, brass, or nylon (for anti-corrosion).
Flange Design: Serrated or smooth to enhance grip.
Locking Mechanism: Some have nylon inserts for vibration resistance.
Applications: Automotive assemblies, electrical enclosures, and piping systems.
Feature | Flange Nut | Standard Nut |
---|---|---|
Load Distribution | Wider surface area | Limited |
Loosening Resistance | High (due to flange) | Moderate |
Corrosion Resistance | Optional (stainless/nylon) | Depends on material |
