Timco Twin-Threaded Woodscrews PZ Double Countersunk 8 x 5/8 Box of 200

This traditional twin-thread woodscrew features a single lead start for fast installation. It is designed for quick driving in soft timber and masonry when used with a plastic plug. Made from C10-18 steel to ensure consistent quality, it employs 60° twin-threads with a parallel shank to enable faster insertion and greater pull-out resistance. The screw is partially threaded from 1 1/4” and above, with a 25° sharp point and a single lead to promote fast start and improved thread acceptance. Surface hardening reaches up to 750 HV to resist torque shear under load, with a core hardness of up to 450 HV for improved ductility.
