Hillman Fasteners 40168 Flat Head Phillips Wood Screw

Product Description

The HILLMAN FASTENERS 40168 is a zinc-plated, flat head Phillips wood screw supplied in a 100-count pack. Each screw measures size 12 by 3 inches, making it well suited for structural fastening applications where deeper thread penetration and a flush countersunk finish are required. The zinc coating provides corrosion resistance suitable for interior framing, cabinetry, and general wood construction. These screws are a standard trade-supply item installed by carpenters, millwrights, general contractors, and maintenance technicians working with dimensional lumber and engineered wood assemblies.

These flat head Phillips wood screws are used in residential and light commercial construction settings. Typical applications include fastening framing members, attaching wood blocking, securing cabinet components, and general wood-to-wood assembly where a countersunk, flush-surface finish is specified. The size 12 diameter and 3-inch length are common in subfloor, ledger, and structural attachment work where standard bugle-head or drywall screws lack sufficient shank diameter or holding strength.

Key Features

• Size 12 diameter with 3-inch length for deep thread engagement in dimensional lumber
• Flat countersunk head profile seats flush with or below the wood surface
• Phillips drive for compatibility with standard No. 2 Phillips bit tips
• Zinc plating provides corrosion resistance for interior applications
• 100-count pack reduces restocking frequency on active job sites

Compatibility

Designed as a standard size 12 by 3-inch flat head Phillips wood screw compatible with dimensional lumber, plywood, and common engineered wood substrates requiring a countersunk fastener.

Installation Notes

Installation is performed with a No. 2 Phillips bit and a variable-speed drill or impact driver set to an appropriate clutch setting to avoid overdriving. Pre-drilling a pilot hole is recommended in hardwoods or near board edges to prevent splitting. Follow applicable building codes for fastener spacing and penetration depth when used in structural applications.
