TRIO Ultimate Deck Screw

TRIO Ultimate Deck Screw has been designed to outperform standard deck screws in softwood decking such as pressure treated, cedar and redwood in these key areas:

Ultimate Strip-Out Resistance
The Torx TTAP™ drive system offers unmatched stick-fit and wobble-free installation, virtually eliminating fastener stripping during installation or removal. A standard Torx 25 bit will also drive the fastener.

Ultimate Anti-Splitting Resistance
The ThruPOINT™ bores pilot hole during installation, eliminating the wedging effect and splitting caused by standard deck screws.

Ultimate Corrosion Resistance
TRIO’s proprietary coating system delivers 2x better corrosion resistance in salt spray testing than standard deck screws and is UV resistant to eliminate fading over time.  This coating also exceeds the performance of code-required ASTM A-153 galvanized fasteners. 

TRIO Spotter™ Installation Guide*
Much more than a lid, it is a tool engineered to increase fastener installation speed and accuracy.

*Available for the 350 pc bucket only

TRIO is backed by a lifetime guarantee for the life of the decking project. If you are ever unhappy with the performance of TRIO, contact FastenMaster for a full reimbursement.
