Stainless Steel Coupling Nuts

Stainless Steel Coupling Nuts are versatile fasteners designed for joining two threaded rods or studs together in a secure and durable manner. Available in both inch and metric sizes, these coupling nuts offer a wide range of options to suit various applications.

Inch Sizes: The inch-sized coupling nuts are manufactured in diameters ranging from 1/4 inch up to 1-1/2 inch. They are engineered to match the standard inch thread pitches, ensuring compatibility with other inch-sized fasteners. These coupling nuts come in different grades, including 304 and 316 stainless steel.

Grade 304 stainless steel offers excellent corrosion resistance and is ideal for general-purpose applications where exposure to moisture or mild corrosive environments is expected. It provides good strength and durability, making it suitable for a wide range of industrial and commercial uses.

Grade 316 stainless steel is known for its superior corrosion resistance, particularly in harsh and corrosive environments. It contains molybdenum, which enhances its resistance to pitting and crevice corrosion caused by chloride ions. This grade is often preferred for applications in marine environments or where exposure to saltwater or chemicals is a concern.

Metric Sizes: The metric-sized coupling nuts are available in diameters ranging from M5 up to M24. They are designed to match the metric thread pitches commonly used in international standards. Just like the inch-sized nuts, metric coupling nuts are offered in different grades, including A2-70 and A4-40 stainless steel.

Grade A2-70 stainless steel is characterized by its corrosion resistance and mechanical properties. It offers good strength and moderate corrosion resistance, making it suitable for various applications in general industries.

Grade A4-40 stainless steel provides enhanced corrosion resistance compared to A2-70. It is particularly resistant to pitting and crevice corrosion caused by chloride ions, making it ideal for applications in marine environments or industries exposed to corrosive chemicals.

Stainless Steel Coupling Nuts, available in both inch and metric sizes, and different stainless steel grades, provide reliable and robust connections for threaded rods or studs. Whether it's for general-purpose applications or specific environments requiring corrosion resistance, these coupling nuts offer the versatility and durability needed for a wide range of projects.
