TIMCO Solo Chipboard & Woodscrews PZ Double Countersunk 4.5 x 25 Zinc Box of 200

A single-thread, countersunk woodscrew designed for use in timber, man-made boards, or masonry when used with a plastic plug. The screw is wax lubricated to aid insertion, offer extra driving torque, and improve corrosion resistance. It features a 40° deep single thread for secure fixing with high pull-out resistance, a 25° sharp point and a single lead for fast starts and better thread acceptance. Notably, all sizes up to 75 mm are fully threaded, while lengths of 80 mm and above have a 70 mm thread length. The double countersunk head helps reduce head shear and facilitates countersinking, and the screw is described as silver in color with a countersunk head.
