The TIMco Twin Thread Zinc Countersunk Woodscrew is designed for general use in softwood and various types of hardwood. It features a double countersunk head and zinc plating for durability and corrosion resistance. The twin thread design enables faster insertion and greater pull-out resistance, making it suitable for a range of timber applications. The screws are made from C10-18 steel and are partially threaded from 1 1/4 inches and above, with a 25° sharp point and a 24° thread acceptance angle for a fast start and improved thread engagement. These components are engineered to maintain strength under load while reducing the risk of head shear during installation.
