Hillman Fasteners 48393 Exterior Screw 3.5in No.10 Gray Ceramic 5lb

Product Description

The HILLMAN FASTENERS 48393 is a gray ceramic-coated exterior wood screw designed for demanding outdoor fastening applications. Measuring 3.5 inches in length with a No. 10 shank diameter, this screw features a sharp point for clean penetration without pre-drilling in most applications. The Fasntite gray ceramic coating provides corrosion resistance rated at 1000 hours of salt spray testing, making it suitable for coastal and high-moisture environments. The coarse thread profile delivers strong holding power in wood and wood composite substrates. Sold in a 5-pound box, this fastener is a practical bulk option for contractors and installers handling exterior trim, decking, siding, and structural wood connections.

These exterior screws are intended for residential and light commercial construction and renovation work where long-term corrosion resistance is required. Common applications include exterior wood framing, fascia, trim boards, fencing, and similar outdoor structural or finish work. The Phillips drive head is compatible with standard No. 2 Phillips bits used by carpenters, general contractors, and siding installers. The 10-year performance warranty backing reflects the durability standard Hillman associates with this coating system.

Installation Notes

Installation is typically performed by carpenters, general contractors, or siding professionals using a standard power drill or impact driver fitted with a No. 2 Phillips bit. Follow local building codes, including applicable sections of the IRC, for fastener spacing and penetration depth requirements on structural and weather-exposed assemblies. Pre-drilling a pilot hole is recommended in hardwood or near board edges to prevent splitting. Avoid using these screws in direct contact with pressure-treated lumber containing compounds that may compromise ceramic coatings unless confirmed compatible by the project specification.
