Fractional Sizes of 316 Stainless Steel Heavy-Duty Hex Head Nuts
Strength and Corrosion Resistance for Demanding Applications
316 stainless steel heavy-duty hex head nuts are engineered for applications that require maximum strength, durability, and superior corrosion resistance. Designed to perform in extreme environments, these nuts are commonly used in marine, chemical processing, industrial manufacturing, and coastal construction where exposure to saltwater, chemicals, and high temperatures is unavoidable. Manufactured from premium 316 stainless steel, heavy-duty hex head nuts provide dependable fastening performance in the most challenging conditions.
Fractional Sizes and Typical Applications
Versatile Fit for Structural and Industrial Fastening
316 stainless steel heavy-duty hex head nuts are available in a wide range of fractional (inch) sizes, allowing compatibility with standard UNC threaded bolts. Common sizes include:
-
1/4″-20
-
5/16″-18
-
3/8″-16
-
1/2″-13
-
5/8″-11
-
3/4″-10
-
1″-8
Each size is defined by bolt diameter and threads per inch (TPI), ensuring proper thread engagement and load distribution. Smaller diameters are often used in equipment assemblies and marine hardware, while larger sizes are ideal for structural connections, offshore platforms, docks, and heavy industrial frameworks requiring high clamping force and long-term reliability.
