Ultimate Deck Screws - #10 x 2.5"

These are an exceptional deck screw, particularly considering their competitive pricing.  They are the only screws on the market manufactured exclusively from high-quality Canadian steel.  This gives them an immediate advantage over competitor's screws that rely on overseas steel of unknown quality.

In addition to higher strength, these screws actually use MORE steel as well - so much more that it is obvious even to the casual observer.  The increased shaft diameter and stronger steel result in 85% more twist strength than comparable box-store screws.

Great strength is only useful if corrosion is kept at bay, and this is a key feature of our Quadrex Fusion screws.  They have a specialized Alumina Coating that is heat-fused to a Zink base plating, providing maximum resistance to the harsh chemicals in modern ACQ pressure-treated lumber.
