Details
The U2 CS is the next generation of construction screws that are replacing lag screws. 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.
