Product Overview

Our A2/A4 Stainless Steel Dome Cap Nut combines sleek aesthetics with industrial-grade performance for applications requiring hygiene, safety, and vibration resistance. Featuring a smooth, rounded dome cap to prevent snagging and a self-locking nylon insert (optional) for anti-loosening, this nut is ideal for food processing, medical devices, marine equipment, and architectural installations. Crafted from 304 (A2) or 316 (A4) stainless steel, it resists corrosion, bacteria buildup, and harsh chemicals while maintaining a polished, professional appearance.

  • Safety & Aesthetics: Rounded top eliminates sharp edges, ideal for public spaces or high-touch equipment.

✅ Anti-Loosening Mechanism

  • Nylon Insert (Optional): Self-locking action prevents loosening under vibrations (temp range: -40°C to 120°C).
  • All-Metal Serrated Flange (Optional): Bites into surfaces for reusable, high-temperature applications.

✅ A2/A4 Stainless Steel

  • 304 (A2): General corrosion resistance for indoor/outdoor use.
  • 316 (A4): Molybdenum-enhanced for marine, chemical, and saltwater environments.
