Hillman Fasteners 48615 Ceramic Exterior Screws No. 10 X 4 in

Product Description

The HILLMAN FASTENERS 48615 is a 5-pound box of No. 10 by 4-inch Power Pro Bronze ceramic-coated exterior screws designed for outdoor structural and decking applications. Each screw features a self-drilling point that eliminates the need for a pilot hole, a Star drive head for high-torque engagement, and a Borefast thread profile engineered for rapid seating in wood substrates. The ceramic bronze coating is rated to 2000 hours of salt spray resistance, making these fasteners a practical choice for coastal and high-humidity environments where corrosion is a primary concern. Contractors, carpenters, and deck builders typically specify screws at this performance tier for pressure-treated lumber and composite framing.

These screws are suited for exterior wood construction including deck framing, fence assembly, ledger attachment, and general outdoor carpentry. The knurled shank section beneath the head reduces the splitting force transmitted to the wood fiber as the screw seats, which is particularly useful when fastening near board ends or in dense lumber species. The 5-pound bulk pack supports production-volume work where per-fastener cost and reduced reorder frequency matter. This box contains 4 package units per box.

Key Features

• Ceramic bronze coating rated to 2000 hours of salt spray resistance for exterior and coastal use
• Self-drilling point eliminates pilot holes in most wood substrates
• Star drive head provides positive bit engagement and reduces cam-out under load
• Borefast thread geometry designed for fast, consistent seating in wood
• Knurled section under the head reduces splitting pressure near board edges
• Lifetime warranty as stated by the manufacturer

Compatibility

Designed as an OEM-style exterior wood screw replacement suitable for general outdoor framing, decking, and fence construction applications where a No. 10 diameter, 4-inch length ceramic-coated fastener is specified.

Installation Notes

Installation is typically performed by carpenters, deck builders, or general contractors using a power drill or impact driver fitted with a Star bit. When fastening into pressure-treated lumber, confirm the ceramic coating rating is appropriate for the preservative treatment level used, as ACQ and similar treatments accelerate corrosion on insufficiently rated fasteners. Drive screws perpendicular to the work surface to ensure full thread engagement and proper seating of the head. Follow applicable building codes, including IRC deck construction guidelines, for fastener spacing and edge-distance requirements.
