Features

  • Designed to be used as a “rescue screw.” This fastener will replace nails or smaller diameter fasteners that have loosened & backed out of steel roofing over time.
  • 5/16 HWH with bonded sealing washer will completely cover existing hole, even if elongated by movement in the metal roof.
  • Type 17 point will help clean the existing hole so that oversized threads can tap & generate maximum holding strength.
  • EPDM rubber is vulcanized to the steel washer to prevent delamination & form an excellent seal even when driven at an angle.

FOR PROPER INSTALLATION, THE USE OF IMPACT DRIVERS ARE NOT RECOMMENDED FOR POWDER COATED OR ANY WET PAINTED FASTENER.

PULLOUT & PULLOVER VALUES ARE DETERMINED IN THE ST FASTENING SYSTEMS ENGINEERING LABORATORY USING STEEL PANELS/FRAMING & WOOD DENSITIES WHOSE STRUCTURAL PROPERTIES ARE FOUND IN PRESENT DAY PRODUCTS.
