Stainless Steel Flange Nuts
🔩 Stainless Steel Flange Nuts
Stainless steel flange nuts are hex nuts with an integrated flanged base that acts like a built-in washer to distribute the clamping load. They are widely used in high-vibration and corrosion-prone environments such as piping, automotive, marine, and chemical industries.
✅ Key Features:
Flange base: Provides greater bearing surface, reduces risk of damage to mating surfaces.
Optional serration: Some have serrated flanges for anti-loosening under vibration.
Corrosion resistance: Ideal for outdoor or chemical environments.
