There are several key factors to consider when selecting a nut for heavy-duty applications, including material strength, corrosion resistance, and vibration resistance. The following types of nuts are generally suitable for heavy-duty applications:
Hex Flange Nut: This nut has an additional flange that provides a larger contact area, thereby distributing the load and reducing the risk of damage. It is often used in heavy machinery and structural applications.
High Strength Nuts: These nuts are usually made of high-strength steel (such as grade 10.9 or 12.9) and are suitable for use in high-load environments. Common high-strength nuts include hex nuts and round nuts.
Nylon Lock Nut: This nut has a nylon ring embedded in the internal thread to prevent the nut from loosening under vibration or impact. It is ideal for heavy equipment, especially in vibrating environments.
Super High Strength Nuts: For example, nuts made of alloy steel (such as A325 or A490), which are designed for high-load and high-pressure environments and are widely used in bridges, buildings and other heavy equipment.
Square Nut: Suitable for some specific heavy-duty applications, especially when connected to large-sized equipment, square nuts provide a larger contact area and better torque transmission capacity.
When selecting nuts, in addition to the material and type, factors such as corrosion resistance, vibration resistance and whether a locking device is required should also be considered according to the actual application environment. If working under extreme conditions, it is best to choose high-strength nuts that meet relevant industry standards and ensure that the matching bolts and other fasteners are also suitable for heavy-duty applications.
