Hillman Fasteners 48622 Stainless Exterior Screws 2.5in X 10

Product Description

The HILLMAN FASTENERS 48622 is a box of 12 Power Pro stainless steel exterior screws designed for demanding outdoor fastening applications. Each screw measures 2.5 inches in length at size 10 and features a self-drilling point that eliminates the need for pre-drilling in many common substrates. The star drive recess provides positive bit engagement and reduces cam-out. A knurled shank section below the head displaces wood fibers rather than splitting them, making these screws well suited for hardwoods, composites, and dense exterior lumber. The stainless steel construction has passed 1500-hour salt spray testing, confirming long-term corrosion resistance in coastal and high-moisture environments.

These screws are intended for exterior wood-to-wood and wood-to-substrate connections in residential and light commercial construction. Typical applications include decking, fencing, trim work, siding, and exterior framing details where corrosion resistance is a code or performance requirement. The self-drilling Borefast thread geometry reduces driving torque and speeds installation. Contractors, carpenters, and experienced DIYers working in wet or salt-air environments will find these a direct fit for projects requiring a corrosion-rated mechanical fastener.

Key Features

• Stainless steel construction rated to 1500-hour salt spray resistance for coastal and exterior use
• Self-drilling point eliminates pre-drilling in most exterior substrates
• Star drive recess reduces cam-out and improves torque transfer
• Knurled section below head prevents wood splitting during installation
• Borefast thread geometry reduces driving resistance and speeds fastening
• Backed by a lifetime warranty from the manufacturer

Compatibility

Designed for exterior wood-to-wood and wood-to-substrate fastening applications including decking, fencing, trim, and siding where a corrosion-resistant, self-drilling screw is required.

Installation Notes

Installation is performed by general contractors, carpenters, and finish trades using a standard star drive bit at the appropriate size. Verify bit size before driving to avoid stripping the recess. Maintain proper fastener spacing per applicable building codes and lumber manufacturer guidelines. Always follow local building codes regarding fastener type and corrosion rating for exterior structural connections.
