The Sure-Seat Screw is a patented fastener used to connect multi-layer panels and building components, like Atlas CrossVent, Hunter Cool-Vent, GAF/Cornell ThermaCal and JohnsManville Nail Board.

Sure-Seat Screws are an essential component to securely fasten Plenum-Panels in CLT and mass timber construction.  

The screws drill through the upper layer making a washer and seat firmly on the supported layer for a solid and sure connection.

Sure Seat Screws are useful for many applications, including the hollow, light weight PlenumPanel used for CLT/Mass timber.
