The new improved thread design drills easier with LESS MUSHROOMING in composite lumber.

CapSure® Capstock Composite Deck Screws are engineered specifically for composite decking applications, featuring an improved thread design that drills more easily while reducing mushrooming in composite lumber.

The T-20 Star Drive helps eliminate driver bit cam-out for smoother installation, while the trim undercut head traps loose material as it countersinks for a clean finished appearance. Top threads are designed to push composite material back into the deck surface to minimize mushrooming, and the deep Tri-Thread design delivers superior holding strength. A Type-17 point provides a quick, efficient start during installation. Available colors include gray, tan, red, and brown to coordinate with a variety of decking finishes.
