Stewart Fastener J1440WPFZ Flat Head Wood Screw No. 14

Product Description

The STEWART FASTENER J1440WPFZ is a No. 14 flat head wood screw with a 2.5-inch length, designed for heavy-duty fastening applications in wood substrates. The flat head profile sits flush with or below the surface after installation, making it a go-to choice when a clean, low-profile finish is required. This screw size is well-suited for structural and finish carpentry tasks where larger-diameter fasteners are needed to carry shear load or secure thick material assemblies. Tradespeople in construction, millwork, and general contracting reach for this size when standard No. 10 or No. 12 screws are undersized for the application.

This screw is appropriate for use in residential and commercial construction, rough framing attachments, cabinetry, decking substructure, and general wood-to-wood fastening where a flush or countersunk finish is specified. The 2.5-inch length provides adequate thread engagement in standard dimensional lumber and engineered wood panels. It is commonly installed by carpenters, general contractors, and maintenance technicians working across a range of wood assemblies.

Key Features

• No. 14 diameter for high-load wood fastening applications
• 2.5-inch length provides deep thread engagement in dimensional lumber
• Flat head design seats flush or countersunk for a clean finished surface
• Sized for applications where smaller-gauge screws are insufficient

Compatibility

Designed for general wood fastening applications including dimensional lumber, plywood, and engineered wood panels where a No. 14 flat head screw is specified.

Installation Notes

Installation is typically performed by carpenters or general tradespeople using a power driver or hand screwdriver with the appropriate bit. Pre-drilling a pilot hole is recommended for hardwood species to prevent splitting and to ensure proper seating of the flat head. Always select the correct driver bit size to avoid cam-out and fastener damage. Follow applicable local building codes for fastener spacing and load requirements.
