Why Bonded EPDM Washers?

The bonded EPDM washer fuses rubber and metal to create a secure, water-tight seal. EPDM (Ethylene Propylene Diene Monomer) rubber is known for its UV resistance and weather durability, making these screws perfect for exterior metal applications where leak prevention is critical.

Ideal Applications

• Roofing & Siding Installations
• Light Commercial & Residential Metal Projects
• HVAC & Ductwork Construction
• Automotive & Mechanical Repair
• Bulk Needs for Industrial & Fabrication Settings

Advantages of Hardened 410 Stainless

Hardened 410 stainless steel delivers a strong combination of high tensile strength and moderate corrosion resistance. It’s more wear-resistant than standard austenitic (300-series) stainless, making it ideal for metal-to-metal fastening and other demanding tasks.

Installation Tips

• Apply steady pressure so the #3 self-drilling tip can engage quickly.
• Use a 5/16" Magnetic Nutsetter for convenient screw placement.
• Maintain a perpendicular approach to ensure even drilling and washer contact.
• Avoid over-torqueing to preserve the EPDM washer’s sealing capability.
