Timco Solo Countersunk Woodscrews are versatile screws designed for use in various types of timber, man-made boards, or even masonry when paired with a plastic plug. These screws feature a double countersunk head, which minimizes the risk of head shear and aids in achieving a smooth countersunk finish. For enhanced performance, they are wax-lubricated, reducing insertion time, increasing driving torque, and improving corrosion resistance. The 40° deep single thread design ensures a secure fixing with high pull-out resistance. A 25° sharp point and single lead facilitate a quick start and better thread engagement. All sizes up to 75mm are fully threaded, while lengths of 80mm and above have a 70mm thread length. These screws have a Zinc & Yellow finish and a double countersunk head type. They are made from Carbon Steel and are partially threaded. The driver bit size is PZ3. The size is 6.0 x 200mm, with a thread diameter of 6.0mm and a thread length of 70mm. Suitable for softwood, chipboard, MDF, and masonry (with plug).
