Hillman Fasteners 48390 Fasntite Gray Ceramic Exterior Screws

Product Description

The HILLMAN FASTENERS 48390 is a 5-pound box of Fasntite gray ceramic exterior screws designed for outdoor fastening applications in wood framing, decking, and structural assembly. These No. 10 x 3-inch coarse-thread screws feature a sharp point for self-starting penetration and a Phillips drive head for standard bit compatibility. The gray ceramic coating provides corrosion resistance rated at 1,000 hours of salt spray testing, making them suitable for exposed exterior environments. Contractors and installers working on decks, fences, siding, and outdoor structures rely on this coating grade to meet code-driven durability requirements.

These screws are suited for residential and light commercial exterior applications where long-term corrosion resistance is required. Typical install scenarios include pressure-treated lumber fastening, deck framing, fence construction, and exterior sheathing. The 3-inch length and coarse thread profile are well matched to dimensional lumber connections. The box contains 5 pounds of fasteners and is sold in cases of 4 boxes, making it practical for larger jobs requiring bulk quantities on site.

Key Features

• Gray ceramic coating rated for 1,000 hours of salt spray corrosion resistance
• No. 10 x 3-inch coarse thread for reliable bite in dimensional lumber
• Sharp point for self-starting installation without pre-drilling in many applications
• Phillips drive compatible with standard No. 2 Phillips bits
• 10-year corrosion resistance rating for exterior exposure
• Bulk 5-pound box format reduces restocking frequency on large jobs

Compatibility

Designed for exterior wood fastening applications including pressure-treated lumber, deck framing, fence construction, and outdoor structural assemblies where a corrosion-resistant coarse-thread screw is specified.

Installation Notes

Installation is performed by carpenters, general contractors, and skilled tradespeople using a standard No. 2 Phillips bit and a variable-speed drill or impact driver. When fastening into pressure-treated lumber, verify that the ceramic coating grade meets local building code requirements for contact with treated wood chemicals. Avoid overdriving screws, as excessive torque can strip the drive recess or fracture the coating at the head. Follow local building codes and manufacturer guidelines for fastener spacing and edge-distance requirements.
