Hillman Fasteners 48386 Ceramic Exterior Screw Gray

Product Description

The HILLMAN FASTENERS 48386 is a ceramic-coated exterior screw designed for outdoor fastening applications where corrosion resistance is critical. This No. 10 by 2.5-inch screw features a sharp point tip and coarse Phillips drive thread, allowing it to seat quickly into wood and composite materials without pre-drilling in most applications. The Fasntite Gray ceramic coating has passed a 1000-hour salt spray test and carries a 10-year corrosion resistance rating, making it a reliable choice for decking, fencing, siding, and other exterior structural work. Each box contains 12 screws.

This screw is suited for residential and light commercial exterior construction and repair. Typical applications include pressure-treated lumber framing, deck boards, fence pickets, fascia boards, and exterior trim. The coarse thread pattern provides strong pull-through resistance in wood substrates. The gray finish blends with common composite and treated lumber colors, reducing the need for touch-up on finished surfaces.

Key Features

• Ceramic Fasntite Gray coating rated for 1000-hour salt spray resistance
• 10-year corrosion resistance rating for exterior use
• Sharp point tip seats without pre-drilling in most wood applications
• Coarse thread pattern for strong holding power in wood and composite substrates
• Phillips drive for compatibility with standard drivers and bits
• Gray finish suited to pressure-treated and composite lumber tones

Compatibility

Designed as an OEM-style replacement and general-use exterior fastener for wood framing, decking, fencing, and composite lumber applications requiring a corrosion-resistant No. 10 coarse-thread screw.

Installation Notes

Installation is performed by general contractors, carpenters, and experienced DIYers using a standard Phillips No. 2 bit and a variable-speed drill or impact driver. Set the driver clutch to avoid overdriving the ceramic coating, which can compromise corrosion protection at the drive recess. When fastening into pressure-treated lumber, confirm the screw coating rating meets or exceeds local building code requirements for treated-lumber contact. Power down any adjacent electrical systems before working in close proximity to utility lines or panels.
