Fractional Sizes 18-8 Stainless Steel Hex Coupling Nut
Fractional Sizes 18-8 Stainless Steel Hex Coupling Nut
Corrosion-Resistant Threaded Connections for Demanding Environments
The Fractional Sizes 18-8 Stainless Steel Hex Coupling Nut is a premium fastening solution designed to join or extend male-threaded fasteners with strength, precision, and long-term corrosion resistance. Manufactured from 18-8 stainless steel, this coupling nut delivers excellent durability and reliability in environments where moisture, chemicals, or temperature fluctuations can compromise standard carbon steel fasteners.
18-8 Stainless Steel Construction
Strength with Superior Corrosion Resistance
18-8 stainless steel (typically Type 304) is widely used for industrial fastening due to its balance of strength and corrosion resistance.
-
Excellent resistance to rust and oxidation
-
Non-magnetic in the annealed condition
-
Performs well in humid, wet, and mildly corrosive environments
-
Maintains strength and appearance over time
This makes 18-8 stainless steel coupling nuts ideal for both indoor and outdoor applications where long service life is critical.
Fractional Size Hex Coupling Nut Design
Secure Threaded Rod and Bolt Extension
Hex coupling nuts feature an elongated hex body with internal threads that allow two male-threaded components to be joined securely.
-
Thread Type: Fractional UNC or UNF internal threads
-
Sizes: Commonly available from 1/4" through 1" fractional diameters
-
Hex Exterior: Allows easy installation using standard wrenches
-
Full-Length Thread Engagement: Ensures proper load distribution and alignment
The long body design provides added strength and stability compared to standard hex nuts, making it ideal for load-bearing or adjustable assemblies.
