Flat Top Hex Washer Screws

Flat-Top fasteners combine under-cut hex washer heads with EPDM cut-tubular sealing washers. They are a superior and cost-effective alternative to standard fasteners with metal back washers.

One-piece design eliminates damage to painted washer surface and eliminates dissimilar metal washer materials

Ideal for Roof and Wall Applications
  • Flat on top stabilizes socket during installation
  • Higher hex provides positive socket engagement
  • EPDM sealant assures waterproof seal even under harsh conditions
  • Special undercut entraps sealant even when driven at angles
  • Standard Oxyseal II™ long-life coating for added corrosion protection on carbon steel fasteners
