Value Collection WSFI-1804000-100BX Flat Head Wood Screw

Product Description

The VALUE COLLECTION WSFI-1804000-100BX is a size 18 flat head wood screw designed for fastening wood substrates in general construction, millwork, and carpentry applications. The slotted drive head seats flush with or below the surface when fully driven, making it a standard choice where a clean, low-profile finish is required. Manufactured from Grade 2 steel with a zinc plated finish, this screw offers basic corrosion resistance suited for interior and protected exterior installations. Overall length is 4 inches. At 0.1 pounds per unit, it is lightweight and easy to handle in bulk fastening workflows.

This flat head wood screw is used across residential and light commercial construction projects. Typical applications include cabinet installation, furniture assembly, subflooring, framing trim work, and general wood-to-wood fastening. The slotted drive is compatible with standard flathead screwdrivers and slotted bit drivers. The zinc plated finish provides surface protection adequate for dry and low-moisture environments. Licensed carpenters, finish carpenters, and general contractors routinely specify this screw type for interior millwork and structural wood fastening tasks.

Installation Notes

Installation is typically performed by carpenters, finish carpenters, or general contractors using a manual or powered flathead screwdriver or slotted bit driver. Pre-drilling a pilot hole is recommended when driving into hardwood or near board edges to prevent splitting. Ensure the fastener is driven straight and fully seated so the flat head sits flush with or below the wood surface. Do not overdrive, as this can strip the wood or compromise the holding strength of the fastener.
