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.
