Hillman Fasteners 48604 Bronze Ceramic Exterior Screws 12pk

Product Description

The HILLMAN FASTENERS 48604 is a No. 10 by 4-inch exterior-grade ceramic-coated screw engineered for demanding outdoor fastening applications. Built on the Power Pro Bronze platform, these screws feature a self-drilling point that eliminates pre-drilling in most substrates, a star drive recess for positive bit engagement, and a Borefast thread profile designed for fast, clean penetration. The ceramic coating is validated to withstand 2000 hours of salt spray exposure, making it a sound choice where corrosion resistance is a hard requirement. The knurled shank section reduces wood-splitting stress during installation. Each box contains 12 screws.

These screws are suited for exterior construction, decking, fencing, framing, and general outdoor wood-to-wood or wood-to-composite fastening in residential and light commercial settings. The self-drilling tip and Borefast thread reduce the number of steps on the job, which matters when driving volume fasteners in deck boards, rail systems, or exterior trim work. The bronze ceramic finish is appropriate for treated lumber environments where standard zinc-plated fasteners corrode prematurely.

Key Features

• Ceramic bronze coating rated to 2000 hours salt spray resistance
• Self-drilling point eliminates pre-drilling in most wood substrates
• Star drive recess provides high torque transfer and reduces cam-out
• Borefast thread profile for fast seating and reduced driving torque
• Knurled shank section minimizes wood splitting at the entry point
• Lifetime warranty included

Compatibility

Designed for exterior wood fastening applications including decking, fencing, and trim. Suitable for use with pressure-treated lumber and composite materials where corrosion-resistant fasteners are required.

Installation Notes

Installation is typically performed by carpenters, deck builders, or general contractors using a star-drive bit and a variable-speed drill or impact driver. While the self-drilling point reduces the need for pre-drilling, pilot holes are still recommended in dense hardwoods or near board edges to prevent splitting. Always select fastener length appropriate to the combined thickness of materials being joined. Follow local building codes for exterior fastener requirements in structural and deck applications.
