U2 Fasteners #10 x 3-1/2" , T-25U Drive Universal Screw - 50 Pack

U2 fastener™ Universal screw is ideal for replacing those old deck screws. The Universal screw's features work together to drive and secure this screw in many types of materials that are used in residential construction. Features include 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 Universal head 'Burrow Pockets' are dynamically engineered to help countersink into the toughest of materials. Below the smooth shank is the 'Reamer Thread', which enlarges the hole to create a passage when drawing materials together and reduces tension for the screw head.
