The U2 CS is the next generation of construction screws that are replacing lag screws is Structural & ACQ treated lumber compliant in IAPMO report ER-454. The Dome Head enhances the structural capability. The U2 CS has the essential features: the Tapper Point which consists of the Cork Screw Start and Blade Cutting Thread for easy piercing and alleviating strain on the material. The Tight Star Recess system is designed to grasp the U-Bit tightly and can be installed with one hand. Underneath the screw head of the U2 CS the Talon Grip holds the screw tight to prevent loosening and uses its nibs to dig into the material when countersunk. Below the smooth shank is the Reamer Thread, which enlarges the hole in the material to create a larger passage when drawing materials together and reduces tension on the screw head.
The U2 Construction Screw is available in lengths from 1-1/2” to 20” made of hardened steel, and in lengths from 1-1/2” to 8” made of 316 Grade Stainless Steel.
