The VALUE COLLECTION R52001322 is a No. 10 flat head wood screw with a 4-inch overall length, designed for fastening wood components in structural, millwork, and general carpentry applications. It features a Phillips drive recess for use with standard Phillips screwdrivers and power drivers. Constructed from Grade 2 steel with a zinc plated finish, this screw resists corrosion in typical indoor environments. It meets ASME B18.6.1 dimensional standards, making it a reliable choice for tradespeople and contractors who require consistent thread geometry and head profile across large quantities.
This screw is suited for residential and light commercial construction, rough framing, finish carpentry, cabinetry, and general wood-to-wood fastening tasks. The flat head profile allows for countersinking flush with or below the wood surface, which is standard practice in finish applications. Electricians, HVAC techs, plumbers, and general contractors alike use flat head wood screws when securing equipment mounting boards, blocking, and structural backing in wood-framed assemblies.
Designed as an OEM-style replacement and general-use flat head wood screw conforming to ASME B18.6.1, suitable for use wherever a No. 10 by 4-inch Phillips flat head wood screw is specified.
Installation is performed by carpenters, general contractors, and trade professionals using a No. 2 Phillips screwdriver or power driver bit. Pre-drilling a pilot hole is recommended in hardwood applications to prevent splitting and ensure proper seating of the flat head. Always countersink the receiving material to match the flat head angle for flush or recessed installation. Follow applicable building codes for fastener schedules when used in structural assemblies.
