2025.03.05 DD Fasteners Metal Bonded Sealing Washers for Self-Drilling Screws

Advanced Sealing Technology for Optimal Performance

These Metal Bonded Sealing Washers create a significantly stronger seal compared to conventional metal or rubber washers, effectively locking in air and fluid while keeping out dust and contaminants. Their innovative design features a flexible rubber layer that compresses to fill gaps, ensuring a tight, leak-proof seal, while the metal backing prevents the washer from deforming or pushing through the fastener hole.

Key Product Features and Benefits:

🔹 Enhanced Sealing Capabilities

• The bonded rubber layer effectively seals gaps, making these washers ideal for applications requiring air-tight and water-tight fastening.

🔹 Reinforced Structural Strength

• The metal backing prevents excessive compression and ensures that the washer maintains its integrity under pressure.

🔹 Ideal for Larger Fastener Holes

• These washers provide a secure solution for oversized fastener holes, preventing leaks and ensuring structural stability.

🔹 Reusable and Durable

• Designed for multiple uses, provided that the material remains undamaged, offering cost efficiency and reliability.
  
  

Material Options for Diverse Application Needs

✅ Galvanized Steel & EPDM

• Combines the strength of steel with the corrosion resistance of stainless steel, making it a cost-effective alternative for wet and outdoor environments.
• Ideal for general construction and industrial fastening, but has a shorter lifespan as the galvanized coating naturally wears over time.

✅ Aluminum & EPDM

• Highly corrosion-resistant, comparable to stainless steel but lighter in weight and slightly lower in strength.
• Best suited for applications requiring long-term exposure to moisture or corrosive environments.
  
  

Applications Across Industries

✔ Construction & Roofing – Ensures leak-proof fastening in metal roofing and cladding installations.
✔ Automotive & Machinery – Provides reliable vibration resistance and fluid sealing for mechanical assemblies.
✔ HVAC & Plumbing – Prevents air and water leakage in ductwork and piping systems.
✔ Aerospace & Marine – Ideal for high-performance applications requiring weather-resistant fasteners.
