Metric Stainless Steel A4 80 DIN 934 Hex Nut
Metric Sizes of Stainless Steel A4-80 DIN 934 Hex Head Nuts
Maximum Corrosion Resistance for Demanding Environments
Stainless Steel A4-80 DIN 934 hex head nuts are engineered for fastening applications where exceptional corrosion resistance and high mechanical strength are critical. Manufactured from A4 stainless steel—commonly known as 316 stainless steel—these nuts are specifically designed for harsh environments such as marine, coastal, chemical processing, and offshore installations. With superior resistance to saltwater, chemicals, and extreme weather, A4-80 hex nuts deliver long-term reliability in the toughest conditions.
Metric Sizes and Typical Applications
Precision Metric Compatibility
A4-80 DIN 934 hex head nuts are available in a wide range of metric sizes to ensure compatibility with standard metric bolts and threaded rods. Common sizes include:
-
M6
-
M8
-
M10
-
M12
-
M16
-
M20
-
M24
Each size corresponds to the bolt’s nominal diameter in millimeters and features standardized thread pitches for secure engagement. This range of sizing makes A4-80 hex nuts suitable for applications spanning light assemblies to heavy structural fastening.
Common applications include marine hardware, shipbuilding, chemical plants, wastewater treatment facilities, food processing equipment, and outdoor structural systems where corrosion resistance is non-negotiable.
Specifications and Material Properties
Built for Strength and Corrosion Protection
A4 stainless steel contains molybdenum, which significantly improves resistance to pitting and crevice corrosion when compared to standard A2 (304) stainless steel. This makes A4-80 nuts ideal for chloride-rich environments.
