• 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.
