Designed for Most Composite Lumber including Trex®

The Durafast proprietary coating was developed specifically for use in composite wood, and it is capable of withstanding the high temperatures associated with driving into composite material. POZISQUARE Composite Screws are approved for use with most pressure treated lumber and have a Lifetime Guarantee against rust. A conventional screw allows molten material to extrude from under the head creating an unsightly “mushroom”. POZISQUARE has a patented composite thread configuration that pulls the molten material into the hole reducing the mushroom affect and sealing the hole as it drives.

How many screws do you need?

POZISQUARE composite screws are available in three colors; tan for composite that weather to tan or cedar, gray for boards that weather to gray, driftwood, or silver and red for redwood style.They come in a 5 pound reusable plastic container with an ACR square driver bit. Be sure to read the installation instructions before starting your project.
