Fractional Sizes 316 Stainless Steel Hex Coupling Nut
Fractional Sizes 316 Stainless Steel Hex Coupling Nut
Maximum Corrosion Resistance for Critical Threaded Connections
The Fractional Sizes 316 Stainless Steel Hex Coupling Nut is a premium fastening component engineered for environments where corrosion resistance, strength, and long-term reliability are essential. Designed to join or extend male-threaded fasteners such as bolts or threaded rod, this coupling nut delivers superior performance in harsh, corrosive, and marine-grade conditions.
316 Stainless Steel Construction
Superior Protection in Extreme Environments
316 stainless steel offers significantly higher corrosion resistance than standard 18-8 stainless, thanks to the addition of molybdenum.
-
Exceptional resistance to chlorides, saltwater, and chemicals
-
Ideal for marine, coastal, and chemical-processing environments
-
Maintains strength and integrity under temperature fluctuations
-
Excellent resistance to pitting and crevice corrosion
This makes 316 stainless steel the preferred material for applications where failure is not an option.
Fractional Size Hex Coupling Nut Design
Strong, Precise Threaded Extension
Hex coupling nuts feature an elongated body with internal threads designed to securely connect two male-threaded components.
-
Thread Type: Fractional UNC or UNF internal threads
-
Common Sizes: Typically available from 1/4" through 1" diameter
-
Hex Exterior: Allows easy installation using standard hand tools
-
Full-Length Thread Engagement: Ensures uniform load distribution and alignment
The extended body provides greater thread engagement than standard nuts, making coupling nuts ideal for load-bearing or adjustable assemblies.
