Product Description

Heavy-duty marine rivets with 40% hollow core. 316 stainless steel, extra wall thickness. Withstands 1000hrs salt spray. M5-M12 sizes. Electropolished. DNV-GL & ASTM F1136 certified.

Built for extreme environments, these A4 stainless rivets feature a reinforced wall design (40% hollow ratio) that increases shear strength by 30% versus standard rivets. The 316L composition and electropolished finish (Ra 0.4µm) provide maximum resistance to pitting corrosion in saltwater, chemicals, and high-humidity. The 82° flat head ensures hydrodynamic surfaces on ship hulls and offshore structures.

  2. Drilling:
    • Use cobalt drill bits (hole dia = d1 + 0.08mm)
    • Maintain perpendicularity (max 0.5° deviation)
  3. Installation:
    • Hydraulic riveter with force:
      • M6: 3,500-4,000N
      • M10: 8,000-9,000N
    • Bucktail temperature monitor: ≤150°C
  4. Post-Installation:
    • Rinse with fresh water to remove salt residue
    • Apply corrosion inhibitor paste to bucktail
