Products / TRUFAST TL Fastener

The TRUFAST TL Fastener is a high-thread-profile screw with a tapered root diameter and sharp point, designed to mechanically attach rigid insulation board and single-ply membrane to structural cement wood fiber, gypsum, and lightweight insulating concrete roof decks, progressively compacting weak substrate material as it drives for a stronger hold. It is used with the TRUFAST 2-inch TL Seam Plate and 3-inch TL Insulation Plate, and is offered in lengths from 2 inches to over 10 inches.
