The STEWART FASTENER F33-036 is a Number 12 wood screw sold in a jar of 100 fasteners, with each jar counted as a single unit for ordering purposes. At 3 inches in length, this screw size is commonly used in structural and general carpentry applications where deeper thread engagement and holding strength are required. The Number 12 designation indicates a larger-diameter shank suitable for hardwood, softwood, and engineered wood substrates. Installers working in residential and light commercial construction will find this size well suited for framing connections, decking substructures, and heavy trim attachment.
This wood screw is appropriate for trade professionals and experienced installers performing general construction, cabinetry, millwork, and structural fastening tasks. The jar packaging keeps fasteners organized on the job site and reduces loss during high-volume work. Each jar contains 100 screws, and pricing and inventory are managed per jar as a single unit. This format is common in HVAC, plumbing, and electrical rough-in work where wood blocking and equipment attachment require reliable, consistent fasteners.
Designed for use in wood substrates including softwood, hardwood, and engineered wood panels where a Number 12 diameter, 3-inch wood screw is the specified fastener.
Wood screws of this size are typically installed by carpenters, general contractors, or trade professionals performing equipment attachment and blocking work. Pre-drilling a pilot hole is recommended in hardwood or near board edges to prevent splitting. Follow applicable building codes for fastener schedules in structural applications. Drive with an appropriate power driver and bit to avoid stripping the head.
