The TIMco Twin Thread Zinc Countersunk Woodscrew is designed for general use in softwood and various hardwoods. It features a single lead start for fast installation and a 25° sharp point to aid penetration, with 60° twin-threads for efficient thread acceptance. The screw is zinc-plated and made from C10-18 steel, offering surface hardness up to 750 HV and core hardness up to 450 HV for durability. Partially threaded from 1 1/4 inches and above, it is suitable for use with plastic expansion plugs and is intended for soft timber applications or masonry when a plastic plug is employed. The double countersunk design helps reduce head shear and supports countersinking, while the single lead combined with the sharp point promotes quick start and reliable thread engagement.
