Coupling Nuts

  • 303

Hex coupling nuts, also known as rod couplings, are double-chamfered hex nuts available in various widths and lengths. The length of the nut is greater than 2.5D, where D equals the basic major thread diameter. Coupling nuts are used to join together two externally threaded components of equal thread diameter and pitch, often serving as rod couplings for threaded rod.

Material & Sizing Options for Hex Coupling Nuts

Coupling nuts are available in metric and inch sizing options. They are also available in various materials and finish options for enhanced strength and corrosion resistance. When selecting the appropriate material for coupling nuts, it is important to consider the specific application requirements, environmental conditions, corrosion resistance needs, and cost.

A563 Grade A Coupling Nuts

A563 Grade A steel is a low-carbon steel that offers good strength at a lower cost than stainless steel options. Unlike stainless steel, A563 Grade A Steel lacks corrosion resistance properties and may require additional protective coatings for certain applications, like Zinc CR+3. A563 Grade A coupling nuts are available in metric and inch sizing options.

Stainless Steel 304 Coupling Nuts

Stainless Steel 304 is an austenitic stainless steel containing 18% chromium and 8% nickel. Stainless 304 coupling nuts offer good tensile strength and resistance to corrosion in many moderately corrosive environments, making it a versatile solution for many applications.

Stainless Steel 316 Coupling Nuts

Stainless Steel 316 contains 16% chromium, 10% nickel, and 2-3% molybdenum. The addition of molybdenum enhances its corrosion resistance, particularly in chloride environments. Stainless 316 coupling nuts provide excellent corrosion resistance in harsh environments, including marine applications and industrial applications requiring chemical exposure.
