PRODUCT SPECIFICATIONS - These are #4 gauge flat head wood screws measuring 1 1/2 inches in length, featuring a Phillips drive head design. The flat head style allows the screws to sit flush with wood surfaces when fully installed. The tapered body and partial threading make them suitable for various woodworking applications, including furniture assembly, cabinetry, trim work, hinges, and general wood repairs around the home or workshop. MATERIAL & CONSTRUCTION - Constructed from low-carbon steel with a zinc-plated exterior finish. The low-carbon steel provides ductility and toughness characteristics, while the zinc plating adds lubricity to the threads during installation. These small wood screws feature a tapered shank with partial threading, which is the typical design for wood-to-wood fastening. The 1.5-inch length and #4 gauge work with interior wood, particle board, MDF board, and similar materials. INSTALLATION GUIDELINES - These flat-head wood screws are designed for use with standard Phillips screwdrivers or Phillips bits, compatible with both manual and powered drivers. Pre-drilling pilot holes before installation helps prevent wood splitting and ensures proper alignment when joining two pieces of wood together. The flat head design allows the screw to sit flush with the wood surface, which is useful when the surface will be painted or stained afterward.
