Using the most modern manufacturing methods and design techniques, the C2 is a revolutionary high performance multi-purpose screw. Designed to give ultimate performance in a multitude of materials, the patented twin-cut point gives a consistent and rapid "pick-up" and reduces timber splitting. These unique features coupled with a synthetic lubrication and dual angle thread results in 52% less insertion torque and 43% quicker insertion time. NOTE: Twin cut tip from 20mm. Deep recess to prevent 'cam-out', giving a precise and positive drive control on every screw Ribs under head for improved countersinking and to give a smooth and flush finish, also prevents splitting and material damage Dual angle thread for ultimate performance and exceptionally high pull-out resistance Patented twin cut technology for rapid "pick-up" and reduces timber splitting Coated with a high-molecular polymer lubricant that reduces the insertion torque by up to 52% and increases rust protection up to 20 times longer than a standard zinc plating All sizes up to and including 75mm are fully threaded and lengths 80mm and above all have 70mm thread length" Thread Dia. mm: Assorted Length mm: Assorted Thread Length mm: Assorted Head Type: Double Countersunk Recess Type: Pozi Point Type: Twin-Cut Driver Bit Size: PZ2 Finish: Zinc & Yellow Material: Carbon SteelSize - 1798 Pieces Timco C2 Strong-Fix Premium Multi-Purpose Screws - Assorted Trade Case - PZ in Yellow
