Heavy Hexagon Nuts Made of A194 2H with Blue PTFE Coating

Heavy hex nuts, also known as HHN, and screws, bolts, screws with each other's use, play a role in connecting fastening machine parts.Heavy hexagon nuts are nuts with a hexagonal shape and a threaded hole, which are usually used in conjunction with bolts, screws, studs, and other fasteners to fasten multiple components together. Their threads are typically standard right - hand threads, and they can be made in metric or unified inch thread specifications, including coarse - thread series (UNC) and fine - thread series (UNF).

Product Features

High Strength and Durability: Usually made of high - quality materials such as carbon steel, stainless steel, or alloy steel, they have high tensile and fracture strength as well as hardness. For example, stainless steel heavy hexagon nuts are available in grades such as AISI 304 and 316, while alloy steel ones often comply with standards like ASTM/ASME A/SA 193/194 B7.

Large Contact Area: Larger and thicker than standard hexagon nuts, they have a larger contact area with the connected components. The hexagonal design can be closely combined with the relevant bolts, increasing the friction between the bolt and the nut, which is beneficial to evenly distribute the load and enhance the stability of the connection, and has a good anti - loosening effect.

Easy Installation and Removal: Thanks to their hexagonal structure, they can be easily tightened or loosened with a hex key or torque wrench, without the need for specialized tools or techniques, which is convenient for maintenance and replacement.

Product Specifications:

Heavy hexagon nuts need to comply with international standards such as DIN, ASTM, and BS. Their length ranges from 3mm to 200mm, and the size covers M3 - M56 or 3/6" to 2", and custom sizes are also available.

Surface Treatment: In order to improve corrosion resistance and other properties, heavy hexagon nuts can undergo various surface treatments, such as hot - dip galvanizing, zinc plating, zinc flake coating, black oxide, and Xylan coating.

Application Scenarios: Heavy hexagon nuts are widely used in the construction and engineering fields, and are often used in conjunction with high - strength bolts such as A325 and A490, and are suitable for connecting metal beams, girders, and other components. They are also commonly used in industrial machinery, oil and gas, aerospace and other industries, especially in occasions that require stable connection and durability.
