About Drill-Tec™ #12 Purlin Fasteners
The specially designed ¾” long pilot point prevents the existing metal roof panel from “jacking” up the threads during the drilling operation, thereby reducing point burnout and breakage.
Note: For detailed fastening instructions, please refer to the GAF Roofing/Attachment System Mini-Manual at gaf.com.Product Documentation
