    The retrofit-friendly RetroDriller fastener features 3 inches of thread, a #3 square drive, and a sharp 0.5-inch drill point for fast and easy installation. It can cut up to 3/16 of an inch into structural purlins and is available in lengths of 4, 5, 6, 8, and 10 inches.

    Each fastener is finished with a corrosion-resistant coating that exceeds FM Approval Standard 4470 for red rust after 30 Kesternich cycles. It’s ideal for securing TPO single-ply membrane to structural purlins in standing seam metal roof retrofit.
