T17 Phillips Countersunk Head Double Thread Universal Screw 4.2×42–45 Z/Y

Product Overview
This product is a multicolored zinc-plated multi-purpose self-tapping screw, manufactured from heat-treated C1022 carbon steel. It features a PH2 Phillips drive, a countersunk flat head, a double-thread design, and a T17 cutting point. Unlike single-purpose drywall screws or wood screws, it is suitable for three types of substrates—sheet materials, solid wood, and thin light-gauge steel—making it a versatile fastening accessory for home decoration, ceilings, cabinetry, and general woodworking.

Whole-home custom cabinetry: Assembly of MDF, particleboard cabinets, and back panels.
Wood veneers and integrated wall panels: Secured to plywood substrates or light-gauge steel frameworks.
Indoor light woodworking, decorative trim, and base layer backing installation.
