Timco Countersunk Woodscrews 8 x 3/4 Inch Zinc 540 Pack

A traditional twin-thread woodscrew designed for quick installation, optimized for soft timber applications and capable of masonry use when paired with a plastic plug. This screw features a 60° twin-thread profile with a parallel shank to promote faster insertion and higher pull-out resistance. It is partially threaded from 1 1/4 inches and above, and it is made from C10-18 steel to ensure consistent quality. The 25° sharp point with a single lead start provides a fast initial bite and improved thread acceptance. Surface hardening up to 750 HV helps prevent torque shearing under load, while a core hardness of up to 450 HV contributes to improved ductility. The finish is silver, aligning with common hardware aesthetics and corrosion resistance expectations. Overall, this fast-start, robust woodscrew is suited for soft timber and can be used in masonry when a plastic plug is employed.
